I was looking at putting some wider tires on my stock 08 silverado, it has 275/55/20 and i was wondering if 305/50/20 would fit? or if any one knows if they are to wide. thanks.

Has this issue been resolved? I can also look into this for you. In order to do further research, I will need the VIN for the vehicle. Please feel free to contact me by private message as well. Thank you in advance.

I can fit 37's on a 2" body lift on my 1500 HD
A Z71 with for keys can fit 35-12.50's with rubbing.
But if you ain't rubbin you aint riddin!!!!
But yes 305's will fit o stock rims. but when you start to get bigger rims and wider rims the rim itself begins to rub which in no bueno!
