And what tire shop have you ever experienced "professionals" regarding performance cars and tires?

There is some amazing talent on these threads e.g. Andre who has been incredible in his upgrades.

I have had great luck with tirerack on hi performance tires, but don't think they have encountered Challenger potential mods.


Let me rephrase my question to 2 parts

1 How much room in the wheel wells for wider tires?
2 Has anyony tried bigger tires yet?
