I am running a very nicely set up KW3 suspension set on my 03TT. I want to get a set of 18" track wheels w/o disturbing the suspension tune that is in place.

I am running the 235/35--315/25 set up in 19" presently.
Closest I could figure for 18" match would be 235/40 and 305/30 but finding the rear tires is not easy.

What are you other tt guys running in 18" tire sizes and does anyone have a good solution to my problem?

thanks, John

 

Why don't you run the stock size, 225/40 18 & 295/30 18 on a Michelin Pilot Sport Cup?

 

I was thinking oem size would be off in diameter but its not bad at all. Maybe thats the solution. I am trying to mimic the setup that is dialed in suspension wise but the stock set up in only a couple of tenths off in radius and 1% off in cirucumference.
Would be nice to run a wider rear, but its a good option, thanks

 

If you want to play with tire size try this: http://www.1010tires.com/tiresizecalculator.asp

But I think stock is best for awd, abs, psm...
