What tires are you running that have an inch thick sidewall??
the old general grabbers reds. General doesn't make them anymore, but I wish they still did.
The new KM3's are pretty close at .75" thick sidewall.

I might take that option at a later date, but it'll be a while until I can put the money into a matching spare rim + tire. Other more important expenses ATM.
It's only about 1/3 of the space with my 35, but yeah it does suck. : /
