Another question for Gary on RS6 tires
I'm trying to decide between putting summer tires on the OEM 18" wheels, or getting 19" wheels. I'd like to run Michelin PS2s.
The RS6 requires an XL load rating. The 19" PS2s have it, the 18" in OEM size do not. (On the TireRack website, the PS2s don't even come up when searching by model.) However, the 18" show a service description of 99Y. Can I safely run the 18" PS2s without the XL rating, and would my local tire shop even mount them?
Also, in the 19" size, three different PS2 listings come up, with slight variations in price and availability. Why is that?
Stock:
SP Sport 9000
255/40-ZR18
Serv. Desc: 99Y
Load Rating XL
18" PS2:
255/40-ZR18
Serv. Desc: 99Y
(no load rating listed)
19" PS2:
255/35-ZR19
Serv. Desc: 96Y
Load Rating XL
Thanks.
