mixing tire brands

I honestly don't know, so I'm asking an honest question, I'm not a troll.

so I have 2 bikes, and track them both. Currently running power pures on both bikes. but my 1krr got a nail in the rear (smack in the middle of the tread), and I patched it, it's holding nicely. I wanted to try the pirelli supercorsa on the 1krr, and the BT003RS on my kawi zx6r.

should I just get a matching front and rear set, or can I run my front tire pures with whatever is in the rear.

thx in advance

Matching tires, for your sake... Different tires have different profiles and it will completely throw off you're handling... Just match them up and save yourself the headache and frustration... And I am not a Pirelli advocate by any means, I've had nothing but problems with them, but a lot if people seem to like them.

Good luck and merry christmas

If your putting it on the track its a good idea to use the same brands. But if your just cruisin around town it wont matter much.

If you're not in an upper level at the track it won't be a problem.

His picture is from Thunderhill, so I have to disagree with you guys. He obviously is getting track time in the tires.

Honestly, if it was me, even riding in the street I have to have the tires matched up. I hate riding a bike that doesn't handle right.

Assuming that you track those tires and the speed of t-hill will heat them up quickly, match them up. You are going to be kicking yourself if you yard sale you're bike because you were too cheap/ too lazy to match up fronts to rears....

Remember, different brand tires have different profile crowns (curvature in tire).

i mix on the road.
run recommended pressures 36f/42r psi

always softer stickier tire on front

right now i'm running a power one on front / q2 on back

typically i will run a road 2 on the rear

50 miles plus to the fun roads just blows through the rear, bad!!!

i went on a 10,000 plus mile ride and milked the whole trip on one set of tires, a pure on the front and a road 2 on the rear. worn out when i got home but they made it

track - i don't mix / use matching sets. Start at 30/30 psi then adjust from there

if you're not riding you're wasting ride time!!!

I have been mixing tire brands for many years as have many other Coaches and track junkies... In fact, my favorite set up has a different manufacturer rear and front.

Even after just 1 session, the profile of every tire has changed - just look at the side of the tire that runs the side where the majority of hard turns runs based on the design of the track....

And that's also why many people who do a lot of track days flip tires - it evens out the wear so they can get a few more sessions out of them.

I always match up my tires. But, I like to have the optimal handling characteristics as well.

1st off, the profile of the tire (steepness of crown, shape of tire curvature) does not change "after 1 session." Generally the tire profile will keep uniform and look similar to where it started, even after the tires are smoked.

2nd, people who flip tires are flipping slicks. When you flip a dot track tire, you are upping the risk of a critical tire failure, that's first hand experience...

I have ridden with a lot of really fast guys both locally and internationally, and I have never heard of anyone using different tire brands. The bike simply won't handle the way it would on a matched set...

The simple fact of the matter is tire manufacturers develop their products with performance in mind. When you start messing with the tire combination, you start messing with the handling.

It's about having fun, if you can have fun with you're handling thrown off, go for it. I just know that most people who spend the money on a trackday want to get their money's worth, not go home frustrated thanks to handling issues.

the profile doesnt matter at all. what you need to worry about is the internals of each tire. if you run a 90 degree radial on the front and a 0 degree radial on the back, once you hit triple digit speeds the tires will react differently.

if you are on the street, more than likely you will be fine. you put the bike on the track and are on the faster end of cold molasses, you had better run the same tire. why someone would spend tons of $$$ to go to the track yet skimp on tires is beyond me. tires are the cheapest insurance you can buy.
