Hey guys...first time poster here, so hello to everyone.

I have a question about wheel/tire compatibility. I got an amazing deal on set of Motegi MR4 wheels w/ tires. The wheels are 17" and the tire size is 215/50/17. I plugged the numbers into a tire height calculator and compared them against the stock tires and here is the results:

Overall diameter: stock - 25.21" new - 25.46"
Diameter difference: 0.99%
Speedo difference: 0.991% slow

I'm under the impression that these numbers indicate that this size will be fine, but I'm not overally experienced in this department so I'd like to get someone's opinion.

I have an 08 xD thats basically stock.

Thanks
