Its time to get some new rubber and after many hours debating, I'm going to the darkside. I have narrowed it down to a few tires, but would like any input on them. All are for car or vintage car, except the Excelsior which is listed for motorcycles in 18" and 19" on Coker's website, but car in 15". ?
? Below is some info and pics. Thanks!
For reference the stock tire is the IRC GS18
140/80-15: 24.0945" Diameter, 5.03937" Width
1. Firestone F560
135R15: 23.57" Dia., 5.00 Width
145R15: 24.30" Dia., 5.60 Width
2. Michelin XZX
135SR15: 23.50 Dia., 5.00 Width (technically the ZX)
145R15: 24.30 Dia., 5.60 Width
3. Nankang CX668
135R15: 23.5 Dia., 5.2 Width
145R15: 24.2 Dia., 5.7 Width
4. BF Goodrich Blackwall Silvertown
500-15: 24.38 Dia., 5.10 Width
5. Excelsior All Black
550-15: 25.87 Dia., 5.25 Width
*I included two sizes on the radials because the widths match on the 135s, but the height is 1/2" short, where the 145s are about correct height, but slightly wider, and I am still going back and forth as to which would be better.*
