I have 4 18x8.5 Breyton Competition Wheels which were just professionally refinished. 3 of them have 235-40-18 Kuhmos, the 4th tire was ripped when the company mounted the wheels. So you'll need to buy a 4th tire ($114 @ tirerack). The tires are 85%.
I need 17inch wheels for my 944. I'd like to trade. Located in CT. Else, I am open to offers. Wheels are mint. Just paid $500 for professional refinish at Precision Wheel in Branford, CT.
Thanks.
