My XJR came with a set of rims and snows but it seems that they are not the same tires. Seller had a blow out on one of the originals so he replaced a pair with different tread pattern. Question is should I put the assemetrical pattern up front or the symetrical pattern there? Both are dead even on treadwear, both Michelin's of similar characteristics according to tirerack.

 

Assyms, from my experience 308's tend to tramline and wonder about on sym tyres. Try both and see?
