Probably a 245/40/20 (I think from memory) on it, can I get my speedo re-calibrated on an all wheel dyno, and if so, will it require a flash tuner, and a tune, thus voiding my warranty?I would love to slug a set of 22's on it, but think towing on 22's is gonna destroy the rear tyres.Cheers.

More important than warranty. Link to comment https://www.fordxr6turbo.com/forum/topic/71757-speedo-calibration/#findComment-1057302 Share on other sites More sharing options...
