Hey guys, one quick question

Hey all, im new to the forum here, i was just wondering how big of a tire i can get with a 2001 silverado with stock rims. I have 245s right now, but i was wondering if i can get something like 275 or 295s in the back and then just keep the 245s in the front. thanks.

If you have the stock 6.5" rims, then 255 is as wide as you can go!
