and nobody seems to be able to get them to air up. I have visited just about every tire
shop in town including the dealer but to no avail. They tried everything in the book
except the lighter fluid trick.

on the rear wheels though.
At first I thought (and they said) the issue was with the 245 tires but they couldn't get
the 235 tires to seal either. I'm really stuck at this point and I guess the worst
case scenario is to give the Michelin 4S rubber a try.
Thank you in advance for your advice and suggestions.
Cheers,
