Machine is a 99 500 Magnum 4x4 it came stock with Front 25x8x12 and Rear 25x11x10 tires and I want to buy new tires and was thinking of jumping up a size and whats got me stumped is being a 4x4 I thought ALL the tires needed to be the same size so the transfer case don't get pooched, how do they run a 10" & 12" rim and have it NOT blow? How do I pick out the next size up without doing damage to the ATV/ what sizes can I run for 25's & 26's. Thanks
the height of you tire is 25" that is right, you 8 and 11 are the width of you tire, and 12 and 10 are rim sizes, i am suprised that the rim sizes would be different, but that is what the numbers stand for

Polaris used 10" rear wheels for several years. They were also (if I recall correctly) 2.5" wider and made a nice round profile on the tires just like the fronts. 12" wheels give you a different profile something like switching tires from 70Spam wordSpam word Spam wordSpam word Spam wordSpam word Spam wordSpam word s to 40Spam wordSpam word Spam wordSpam word Spam wordSpam word Spam wordSpam word s on a car. They were round, now they're ovals.
Spam wordSpam word Spam wordSpam word Spam wordSpam word Spam wordSpam word = ratio of height to width, i.e., a "50" is only 50% as tall (ground to wheel) as it is tall. Look at some "wide oval" muscle car tires compared to standard, then look at the quad to see what I mean.
When my friend got his Blackwaters, the front and rear wheels were both 7" wide. The front tires stuck out 1/2" on each side, and the rear tires stuck out 4 times as far. It looked really weird to have a wide oval rear and round profile front, but the manufacturers only want to make one size wheel, and it cuts down on inventory for the dealers too.
I understand how to read the tires & rim sizes and they are the correct rim sizes from factory OEM thats why I don't understand the 10-12 combo. Yep the rear has a nice profile like the front tires do but it just seems as though the transfer case would get damaged just like a 4x4 pick-up would. So I'm ok if I run the same size front & rear rims? Its not like the differentials have different gearing to make up for the different size rims from the factory or do they???? Thats my worry if I go to the same size all around.
