Josh Posted June 3, 2011 Share Posted June 3, 2011 What size are the wheels first? Quote Link to comment Share on other sites More sharing options...
Dnk Posted June 3, 2011 Share Posted June 3, 2011 Are the wheels 18 x 8.5 front and 18 x 10" rear ? If so the optimum sizes are Front 235 or 245 Rear 265 or 275 Quote Link to comment Share on other sites More sharing options...
Guigsy Posted June 3, 2011 Share Posted June 3, 2011 My rears are the same width but I've got 255 on them and they look perfect. Which is interesting. I wonder if I'll stop spin in 1st with some slightly bigger. I always imagined they would look odd Quote Link to comment Share on other sites More sharing options...

I was hoping the 285 and maximum 245 on the front to keep the good traction ? the calculator is sayin 285/30 on 18" wheels Isnt 30 too low ??
