Guys
i just purchased my first (2004 H2 with 110000 kms). I dont want to change the original rims and wanted to put wider tires.
What will be the widest tire size I can put on original rims as I am going to powder coat the rims. I think it has 315 70 17 right now

 

Personally I wouldn't go wider than 12,5" on the 8,5" stock rims.

 

These will fit with no mods. Good looking and nice riding tires about 208 each.
