2021 Tire thread

Looking for a new set of tires for a the 95 250. I used the search function and only came up with tire suggestions / info that's over a year old.

Looking for tires that are stock sizes. Preferably not bias ply. I'm not concerned with wear but need a tire that works well for canyon carving. I run battlax S21's on my GSXR and love the way they hold in corners. I've been searching all the usual sites and am having a hard time finding something.

Front Tire: 100/80-16
Rear Tire: 130/80-16

Not interested in changing the swing arm, wheels, etc. my 95 is bone stock with 2300 original miles and about as flawless as you can get. Anything new out this year you are running? I see lots of 16" wheel tires that are listed as "scooter" tires. Anyone ever tried them?

I know what you mean about finding good rubber for the 16s. I just did the newgen conversion to solve all those headaches.

I went with the Pirelli Sport Demon tires. There were mounted yesterday and I'll pick them up later today. I'll give an update on what I think of them after a few miles are logged.

According to the guys at the tire shop, our options are the Pirelli's, Shinko's or Dunlop's without doing any modification to the fender.

That's silly. Bridgestone BT46 are available in 100/90-16 front and 130/90-16 rear. I've been using BT45s for years, and will go to BT46 as required.

I'll be interested in how the Sport Demons perform for you. I put them on my Moto Guzzi a few years ago and at first they were excellent. Then the front tire quickly got the usual triangular shape and handling suffered noticeably. The rear wore out at 3,800 miles. That was bald in the middle too, not just down to the wear bars.

Well that sucks, for me. Just picked up the Pirelli's mounted and balanced.

The whole purpose of this thread was to find out what is out there in a 16 and does not require any modification to the fender. I'll run the sport demons and see how they do. The BT46's will most likely be the next set put on.

You may find that the Sport Demons are great tires for a Ninja 250 and my problems were due to a 500 lb. motorcycle.

Have you read the tire section of the FAQ? It's getting old, but some of the information may still apply: https://faq.ninja250.org/wiki/What_t...fit_the_250%3F

Yes, I started there. It hasn't been updated in a long time. I was looking to the most current info on what's available.

I'm a big fan of Bridgestone tires. Currently running the Batlax SP21's on my Suzuki. That tire has an incredible amount of grip. Going to give the Pirelli's a shot and put them through their paces in the Santa Cruz mountains. Hope they can handle it.

If they behave like mine did, you'll be very happy with them while they're new.

Keep in mind that you originally asked about 80 aspect ratio tires and the Bridgestones I posted about are 90.

I have Kenda on both my 250, and 91 EX500, have them for many years, it's a good all around tire, and wet weather performance is great.

I've had the BT45s good tire, but didn't last as long as the Kenda.

Did you have to do any modification for the 90 vs 80 aspect ratio?

I can only find Dunlop K630 in 100 80 16 and 130 80 16.

I can find the Pirelli's in 100 90 16 and 130 90 16 but cost a bit more.

An 80 aspect ratio tire is less tall, but not wider than a 90. The width is fixed by the first number, 100 or 130 in this case.

Do you need to modify the fender for the 90 since it's taller?

Ive been using the Michelin City Grip tires in a 100/80 front and 120/80 rear and it has been great! Just switched to the City Grip 2's last week (supposed to be even better water tires, and longer life than previous tires). I get about 2000-4000 out of a rear and 6000-8000 with a front. Just a pro tip, the bike does better with a 120/80 rear. On average a 120 rear is about 3-5 lbs lighter than the stock (City grip 120 is 4lbs lighter!!) Dunlop 130 or other 130's. I've had 130/90, 130/80, 130/70, and 120/80 of different tire brands, on the rear of the ninja 250, and all in all, the 120/80 performed the best in the corners and at higher lean angles and braking and acceleration felt better.

I know I suggested the City Grip 2's, which I think is a great overall tire and I still recommend them... But

I re-read this again, and saw how you mentioned you like the Battlax series... Well, it looks like Bridgestone came out with a performance scooter tire call the Bridgestone SC! I'd love for you to get a pair and let me know how they work out! They look good and so does the price!
https://www.bridgestone.com/products.../detail/pr036/

Or a third option, is the Pirelli MT75's. I have owned the Pirelli tires before, and while the grip is outstanding, they only lasted 3,500 miles before having to get a new front and rear (ran through 2 rears in 3,500 miles). So I would say they are WAY to soft. Also, I did experience overheating and sliding, if the tire was kept at high speeds (85-100 mph in high speed sweepers, for 2 hours straight) it starts to get a little greasy, but if i drop my speed for a few minutes, and ease of the corners, they cool back down within a few minutes.

That's not a lot of miles. I realize miles isn't necessarily the primary feature of tires, but I'd hope to do better than that on a light motorcycle like a 250.

Well a little about me and my riding... I am a tool when I ride, so I push the outer limits of the bike, pretty regularly... I carry saddlebags and luggage on my bike (on average about 20-30 lbs of luggage, and up to 50 lbs when traveling far).. I also ride at a fast pace while on back roads, and a lot of the roads around where I live are built for 90-120 mph speeds in the corners, so I am regularly keeping the bike up towards 90+ mph pretty much all the time when I'm riding in my normal spirited mode and my tire pressure is usually kept in the high 20's front and rear (when 2up I up it to 40 in the rear and 30 up front)... When I ride 2 up with my wife, which I do frequently on the 250 when we go grocery shopping, I usually keep the average pace closer to 80 mph... Now when someone whos normal rides the 250, like my wife for instance, she can get 5000-7000 out of a rear and 10k plus on a front...

Thanks for this, you just described the tires I'm looking for! I dig that you can run a smaller 120 on the back and feel the improvement, I like the direction you're going.

No problem man! I hope you enjoy them! They are fantastic in the rain, and you can brake and lean almost as good as if it were dry outside. Excellent performance tires!

I'm glad to see that 16" is a common enough size in the scooter market. I hadn't thought of them, but there is quite a selection of performance tires there. It's fortunate too as our 16" first-gen wheels are getting rare and the 17" new-gen retrofit looks wrong to me.
Not to mention, going narrower is way cool to me. My main bike is an SV650 and so many kids who get one as their first bike want to make it look like a supersport by fitting a 180 rear tire. What a pointless effort; they just make the bike turn slower and the 160 gives you all the cross-section you need for the lean that bike can reach. I can't wait to get ripping on Palomar or Ortega with this 250 and a 120 rear should be fun with all the Ducatis and R1s.

You all do know you can go with 70 series tires there should be enough room for up to 110 front and up to 140 rear as it only tab bit smaller unlike the 90 series which 10mm taller over the 80 series vs 3mm shorter with 70 series that center difference

Doesn’t 140 rear rub the swing arm and the center stand?

I’m running 130 90 rear and 110 on the front of one bike, and 130 90s front and rear on the other. The 130 90 just fits in the back and front.

Issue I've had with wider-than-stock tyres on pre-gen is it slows down handling. Wider flatter profile makes bike lazier to respond and takes some fun out of riding.

Earlier his year, I bought front ContiScoot tyre in stock 100/80-16 size. Put on about 4K-miles and it'll look like I'll get at least 15K-miles out of this tyre. It also works really well in rain!

My scrambler 250 has the wide tires, but I found the taller rear made up for the width by changing the front steering angle. Plus I live in Kansas so there are a lot more straight roads than twisty ones.

Anybody try these tires yet? I think they're stock tires for some smaller Honda CBs? They come in Ninjette sizes.

I want to keep this one rolling, pun intended! It may be a a mistake on my part but I can’t find a single opinion on the Shinko tires. My use will vary on them as I use the bike to commute to work and have some fun cause there isn’t a straight road around here. So that being said Shinko 740/741 combo any good. I currently have a new irc ss530 on front and a Dunlop k630 on the rear. Stock sizes. Looking for a front tire that doesn’t hunt down every groove in the road and a rear that doesn’t slide around cause it’s 10 years old and hard like a rock lol. Funny thing is they both heat up nicely I thought that they would stick better. I know I need to upgrade the suspension a bit but it’s pointless on these tires.

I've mentioned numerous times I Shinkos are awesome. Built on previous Yokohama plants.

I'm on 5th set of Shinko radials on my CBR600RR and they've all worked great. Used them on both my pre-gen and new-gen 250s. Even on track they've been amazing. Better than original factory tyres.

As for following groves on road, make sure they're NOT overinflated.

Pressure recommendation is corporate CYA lawyer-speak for max-load capacity of tyre when bike is at max GVWR (with passenger) running at top-speed of tyre rating (Z=150mph, W=168mph). Unless you carry passengers and ride at tyre's top-speed constantly, then that pressure is not relevant to your actual riding conditions.

Link to original page on YouTube.

Better to use suggested pressures from tyre-manufacturers themselves. Find similar model to yours and add 10% pressure over max-grip pressure below for street-riding. Best to use max-grip pressure for best braking & cornering performance rather than max-load rating. Which results in poor grip and bad tyre life.

Manufacturer's recommended tyre pressure is just corporate CYA. They know nothing about you or your riding conditions. They are only concerned with product liability. You will never overload a tyre by pumping to max-pressure. That's all they care about.

For DOT rated tires, ALL tire OEMs must list the MAXIMUM cold pressure for the tire to perform at the MAXIMUM rated speed while carrying the MAXIMUM rated gross load without fail for at least 1 hour. That's maximum-speed of tyre-rating, not bike's. So 2.9-bar on Z-rated tyre is for max-weight loading on tyre at 150mph for 1-hr. A W-rated tyre at 2.9-bar is for max-weight load at 168mph for 1-hr.

But performance, traction and safety is something completely different.

You'll also want to start log-book of your rides with model tyres used along with pressure. You'll notice trends with pressure settings that'll give you most traction for braking & cornering. Find actual braking-distance of your actual tyres at different pressures.

Bike manufacturers used to give optimum pressures for each model depending upon tyres used (similar to charts above). But that was too much work and opened them up for too much liability (at least in U.S., what if someone used tyre-pressures for one tyre model with different tyre?).

So about 15-yrs ago, moto makers got together with tyre makers to come up with universal solution of 2.5/2.9 bar pressure for everything! Tyre makers would design for max-load@max-speed at that pressure and moto makers would list that in their manual. It's not optimum setting, but least of all evils.

Never mind that 137kg CB125 @ 116kph top-speed puts lots less load on its tyres than 264kg Suzuki Hayabusa at 300kph (limited). Yet they both have same 2.5/2.9 bar recommended pressure! Ridiculous!

Yeah I hear ya on the tire pressures they are enough to make you crazy between all the max inflation/max load and stuff. I go with what gets the tires warm up quick and stick most. And that varies based on load speed tire composition etc. My Harley says 32 front and 40! Rear! It’s like riding a brick. I use (after lots of trial) around 28-29 front and about 35-36 rear. That’s best for ride and handling for that bike with the oem tire.

I will be trying the Shinko tire on it. I have had them on other bikes with decent results. Pressure in the ninja is at 30 and 32 currently. That’s for commute.

Good, not blindly following "higher authority", literally !!!

Shinko SR740/741 gave me best lap-times using 31/27psi, so you're in ball-park. Tread pattern also makes difference to tram-lining. Longitudinal grooves will grab and hold onto grooves in tarmac. Something like Dunlop Mutants would appear to resist that. It's certainly has good reviews for rain.

Recently best tyre deal yet!

Just put some on my VFR. Hopefully last more than 3-days track!
