Hello,

I am new to the RR family. I just bought a 2011 RRSSC in black. I have gone through every possible thread on numerous websites to find an answer to an issue I am having. If possible I am hoping someone on here can help.

RRSSC came with 21" Black OEM wheels (275/45r21) from I think 13' models. Has the awful 275/45r21 tires on it. Dealer is replacing 3x for me as part of the deal.

1. Issue: Stock oem wheels were Manchester 20" wheels. The tire size should have been 275/40r20. But equating those to the now 21" wheels and tires the speedo should be off about 6mph positive. That is a huge issue for me. I am assuming the RRSs take readings off wheel hub speed here.

2. Should I buy a set of 20" stormer or manchester OEM wheels and then put back the OEM tires and then its normal; or is there a fix for this. Just not wanting to get 3x new 21" tires and then have to buy all new set of 20"s to get it right.

3. What are others doing for this issue or when they jump to 22s.

4. If I keep mine, they are black, where do I get the black OEM center caps other than amazon or eBay. They list them as 63mm caps or 65mm caps. Which are the correct size for RRS wheels?
Thanks for the help

Andrew
