Welcome to the fat tire club. Nicely done! The sidewall seems to be fairly flat, that's the solution to making this work. If those 335's were on an 11", the sidewall would be bowed out big time. Wide tires need the wide rims. I wish I'd gone 12" now.
You'll love the traction!!
Thanks.
You used a spacer didnt you?
Your car was the inspiration for this btw
