Hi! Question here. I have a 1997 Yamaha Big Bear with Front tires size 25x8x12
Rear 25x10x12 stock. I just bought 4 new tires for 80 dollars. What a steal.
Size are AT 270/60r-12 rear
AT 205/80r-12 front on these tires its says
the front size are replacement for 25x8x12 and the rear replacement are for
25x11x12. Question is Can I run the rear tires on my quad without changing the gear ratio?

I know on my 4x4 truck all the tires have to be the same or you won't be able to shift into 4 wheel drive. it just grinds the tranfer case.

thank you

Of course. They are all 25" tall.

 

As long as they are all the same height no problem. You could even have gone to 26" without any issues. And if need be you could always add a K&N air filter.
