I now own a set aof 31 tall by 12 inch wide rear tires for my soon to be baja bug. I think this may have been discussed but what exactly do i need to do to fit them and will it kill the trans quick???

Thanks for the info, i have a 77 bug that will soon be converted to baja. Also it's not too late for me to resell these if that is too big, but i think it should work.

Ive got a 70 with 30s on it and they are only about 3/4 of an inch away from the rear torsion bar housing. You might want to have a look at that. I dont know about the width though. They wont kill the tranny right away, you just wont be able to go up hills very easily and have very little power. I had a stock tranny, 1600 and 30s on the rear and it was a pain accelerating. I went ahead and had my ring and pinion switched out and close 3rd and 4th gears installed also they will give the clutch a work out.

Shit that doesnt sound too good to me. Might be better off getting some 29's.

they will probably be too tall unless you run a body lift or wider arms

they will probably be too wide unless you run wider arms or a highly offset wheel

Well damn probably would have been a good idea to post before i bought them. Running a big offset for the tires will be even harder on the transmission wont it?

the offset will be harder on the suspension components. the diameter and weight of the tire is what is hard on the transmission

alright tires actually measured and they are 29 1/2 inches tall, which works out well. actual measurement for them is 325/60/r15.

325 is pretty wide im thinking it will still need an offset to work. That will obviously be a lot cheaper than arms unless there are longer trailing arms that are around 100-150 for a pair that i dont know about.

most 31 x 10.50 tires are actually about 29.5" tall with 9" of tread width. the numbers always seem to be a bit over estimated, especially when you compress the tire with the weight of a vehicle
