Welcome from another Louisiana guy , I am not recon guy , but have been around a few , I think you can fit 25's under the rear -------- I always go with , listen to everything and believe half of what you hear ------ the best way to know is to try it , my friend bought a Yamaha Timber Wolf 250 2wd for his daughter a couple of weeks back , he came by the house and I let him try on a few different size tires , he found he could fit 26's in the rear and 24's in the front , so he went 25 rear and 24 front , do you have any friends that would let you try on their shoes
