The 02 Q45 I bought has 245/35/20. Its a little too low profile for me. Can I go up to 40 without rubbing and still keep the 20" wheels?

How much space do you have from the wheelwell?

According to the chart I use (which has been accurate so far...) your current overall wheel diameter is 680mm (26.8"). The 40 series will up the diameter to 704mm (27.7"). Grab a tape and see if you have .45" (12mm) of room between your current tire and the lip of the wheelwell (with a bit of extra...) say, 3/4"?

This thing is awesome!

I used it to make sure my current tire/wheel combo would fit. It even takes offset into account!
