Mickey Thompson street radial II

[1971gmcshortbed]

Well after figuring out that I dont want to run 18X8's all the way around, I started looking around. I originally wanted Mickey Thomson Sportsman S/R tires. But after realizing that I cant afford new wheels I called Boyd Coddington wheels.

They can "re-hoop" 2 of my wheels for a not so bad price. I can go from 18X8 to 18X10 or 18X12, I figure if i'm gonna spend the loot I may as well go as wide as I can. However a Sportsman S/R is not made for a 12" wheel (on an 18"). So another tire I found the Mickey Thompson ET street radial II's. I can only find a handful of 345/35 18's. Most are track tires. The ET street radials have a 000 treadwear. So basically they wear out real quick but they stick good.

There are many 335/30 18's but I think they are too short. I would like at least 3 or 4 inches of sidewall. What do you guys think? Has anyone seen a more "streetable" 345/35 18? The pic below is the street radial II I believe the ones on the left are the 345/35.

Anyone have any experience with this or a similar tire? How long do you gus think they will last? Considering I won't race it or drive it real hard. It will have the power but i'm too old to be hot rodding around.
