tire fit help?

[DSJ]

OK My wife has given me the go ahead to get new tires. For background, I have a 83 K30 cut down to 114" wheelbase, D60 14ff and detroit with 4.11 gears. I am currently on 13/36/16 TSL's that are worn out. I am tired of bouncing down the road so I am looking into the Goodyear MTR. I would like to go the 40's but I can't do the gears yet so my question is should I go with the 40's or the 37's?

The 40's are cool, but only come in 17" rim size, Which I didn't like so I went with the new 39.5" IROKs on a 16" rim and saved about $600 over what I could get the MTRs for anyways. As for which size, go bigger now...you'll only regret wasting money on the 37's when you change gears. Plus, this will motivate you to do the gear swap quicker.

I do like the idea of saving money but I do drive this truck every day and I just can't see buying a set of swampers that will wear out in 10,000 miles verses MTR's that will last 20-30,000. I don't know if I got a bad set of swampers or if they are normal but they never could be balanced and seemed if the weather was below 60 to never get round.

I guess we'll see this winter with mine, but I let my truck sit for a week at a time and experience no flat spots.

I'd go with the 40s. I have 38s and I really don't beg for more gear (I have 4.10s too). I would probably go to 4.88 if I had the chance, but I really am not unhappy having 4.10s.
