Yup, no doubt!
I've been getting them either from my wholesale guy (if he has what I want) or tire rack. a little more $$, but...Oh well... Then I have my independent tire store install...they don't seem to be as picky...but their careful and know/respect my expectations.
I know it's not the best scenario, but just bring the tires/rims to them loose...they should put whatever size tire you want on them no questions asked...
Yep...been there, done that...
Going from my Benz 305/25/20 and 255/30/20, the GT's 35 series was a nice cushy ride change for me! I no longer cringe when I see a pothole I can't avoid...It just takes it now with the 35 series, no problem!
