Mix away, Just don't mix bias with radials and be sure to run with the proper psi. Your psi should only increase 10% after warm up. If its more your under inflated, if its less the psi is too high

 

I've done it numerous times without issues of any kind. In fact, I'm getting ready to install a new Michelin C2 on the front with a Dunlop E3 on the back. I'm testing the C2 for tread wear. This applies to bias with bias, not mixing bias with radial, as that would be a bad idea.

 

I have run different brands of tires. Heck on my Night Train I ran a tubed tire up front and tubeless on the rear. No issues.

 

Thanks guys, I guess that's the way I am goung then. Lots of good input and I appreciate it.

 

The dealer just wants you to buy that POS dunlop 408 or whatever they are. I run the dunlop American Elite and love them I had a blowout on the rear last year and the dealer out on a 408 and I couldn't wait for that thing to wear out so I could replace it with an AE. The only handling problem I had was the cupping that is inherent in the 408.

 

Ok, for all you disbelievers, I put a 120/70/21 Micheline Commander II on the front of my bike yesterday and am still running teh stock rear Dunlop. The bike actually handles a lot better now as the Com II tire is much better. I am sure when I do a rear wheel I'll do a matching tire but until then I am rolling with a Michelin front and a Dunlop rear. I'm tempted to sit at the dealer and show people so they don;t buy into the BS they spew.

That has to be one of teh worst sales tactics I have ever heard. And I am in sales but it makes sense to let customers decide what they want, not tell them what they can and can't do. In some instances it is smart to inform customers of potential issues (a tire that is too wide for a rim, etc) however this one still takes the cake.

 

Heck in the old days we ran whatever that rear tire was and the 21" front was always a ribbed straight thread on the front....

 

Suckers are born every minute, but the worst ones are the ones who've been informed otherwise but do it anyway because it was recommended by the dealer as "the right way".
