I'm looking for replacement tires for my 05 SRT10. They originally came with Michelin Pilot. Fronts are 275/35ZR 18 and the rears are 345/30ZR 19. I am finding it difficult to find any tire shops that carry these sizes especially the rears. I'm hoping to find some that are as close to original as possible. If anyone out there has found a reputable tire store(in Michigan) please let me know.
