Sorry in advance for any repeat, I searched, but I'm still looking for some advice.

I managed to run over a large piece of rebar in my 96 D1 and took out the pass front tire. My tires are pretty beat 235/70s and in all honestly it's the exact kick I need to be done with them.

In any case I'm looking into getting General Grabber AT2's due to the rave reviews of them.

Size, however, is plaguing me. My truck is stock, and most of my driving is on the street. No plans for any serious offroading, but I do tow a trailer a bit, and some of it is on questionable surfaces (mud/snow). I was thinking about going a bit bigger then stock, but how big?

235/70 stock size fits of course
245/70 will fit
255/70 couldn't find any info
265/70 will fit with lift, but can it fit with no lift?

I might do a lift eventually, but definitely not now.

Of course, any advice is appreciated! Thanks in advance.

 

Just stick with the stock size, go with a higher load rating and run them at 40 psi.

There is no advantage of going with a larger size if you dont have a lift.

 

.......unless you want more ground clearance. I run 245 75 16. They fit fine, no rub. I did have to adjust 1 steering stop a little. I have a buddy with 255/65, but not sure if the 70 series would rub or not. His are closer than mine.

 

Ground clearance was my thought, I've never gotten stuck, but you never know!

okdiscoguy, you run the 245/75's on your D1 or D2? Would you recommend the 245/75 over the 245/70?

Thanks for the input, and being nice to an obvious noob.

 

I've had sumitomo all-terrains 245/70/16's for over a year, hard right's going over stuff causes VERY minor rubbing, I love 'em

luck,greg

 

What is the actual height and width gain of a 245/75 series tire over a 235/70?
I dont know thats why I ask.

 

Well a 235 to a 245 is a 10mm width gain, ~.4"

235/70 = 28.95"
245/70 = 29.50"
245/75 = 30.45"
265/70 = 30.60"

Going from the 235 to the 245 both in 70 aspect doesn't gain a ton, but the 75 buys almost 3/4" and the 265/70's (that I probably can't fit!) a little more.

 

I have been running my General AT2s for about 25k miles and they have been great. Very little wear with plenty of tread depth left. Not too bad highway noise (esp. compared to BFG ATs) and just a slight drop in MPGs from stock.

I went with the 245/70s as at the time of purchase I had stock suspension on my 96 SE7. I now have an OME HD set up and could envision bumping up to the 245/75 or 265/70 area when these are done. There was a little inside rubbing with the stock set up only when turning to full stop.

As mentioned, there is not much reason to go over the range of sizes that have been discussed without losing more MPGs unnecessarily.

 

Thanks for the info.

 

If you ever want to figure out tire width and height- take section width,divide by 25.4(that's your width), times that by section height in decimal form, times that by 2, and add rim diameter.

245/75/16- 245 div 25.4= 9.64 (tire width) x .75= 7.23 x2 = 14.46 + 16(rim size)= 30.46(tire diameter)
