Ive been looking for some new rear tires for an auto X Im going to in a few weeks. Found a set of 27/68/R18 MICHELIN RADIAL. Would those fit? if not what size would I need? I have an 07 touring btw. I dont know much about tire sizing Thanks

 

Drag racing tire for autocross? No no no. Side walls are terrible. You would be driving on them. Not sure about lateral traction but mediocre at best.

 

thanks for the info david
