I have 20 inch rims 8.5 wide in the front and 10inch wide in the back, what is the max tire i can fit on these?

Thanks

 

I have 255 35 and 295-30 Toyo Proxes04 on mine and my friend has BFG KDW same size up front but 285 30 20 in rear on 10.5 wheels. Looks just fine. Some people do 255 35 and 275 35. All will work. Just make sure you are careful if you pick Falken FK 451 or 452 because they are drifting type tires with real short sidewalls. I had then in 285 30 and they looked like ****. Same size in BFG KDW look awesome. Before you drive away from shop make sure you like the look. Good Luck.

 

I have the BFGs 275 35 rears and 255 35 fronts, Great combo, no problems
