I need to put tires on my 1999 K2500 suburban with a dually rear end. It is not lifted and I don't plan on lifting it unless I need. It currently has 245/75/16 tires. They fit fine and don't rub on each other on the rear axle. I would like to increase the size a little bit if possible. I know a regular suburban can fit 265/75/16 tires. I don't know if those would rub or not if used as duallys. I know the 235/85/16 is about the same height and they fit on the dually pickups but they are not as wide as the 265/75/16. Has anybody used a 235/85/16 on a suburban or used 265/75/16 as a dually?

265 is 0.79" 20mm wider than the 245
285 is 0.39" 10mm narrower than the 245
The 85 and 65 are basically the same diameter so I would guess that is your best bet.

I use the 235/85/16 tire on my Suburban. Works just fine and may get a hair better fuel mileage. Lots of commercial use that size. You might need to do speedo correction, I would think it would add 3-4 MPH from the 245s

I use 265 70 or 265 75 on my K1500. Why do you want to use 235?

235/86R16 is a very common commercial tire. They are easy to get in 10 ply and are cheaper than some of the other sizes. They have a good sized sidewall just not very wide when compared to other off road tires. 235s also work on a dually axle without rubbing. That is why I am considering it. I currently have 245s on the suburban. I would like them to be a little taller and as wide as possible with out rubbing on the rear axle.

My suburban, originally came with 235 when I bought it 15 years ago. Except, all 4 tires were different brand. LOL!!!

Big question for JM is did you notice before you bought it? I have made the mistake of only looking close at one tire till I got home. Had the 4 different tires as well as the 1 not so old and 3 very old ones and the not so old one was the one I looked at the dates on.

I must admit, I was not very good at buying car at that time.
Owning this truck has educated myself about DIY and buying cars in general.
The truck was in a rough shape when I bought it.
Replaced the tires and wheels about 6 months into the ownership.
Read a lot of threads here, especially the FAQ to educate me.

I went ahead and ordered 6 Yokohamas in 235/85R16 from tires-easy.com. I have ordered from them before. The tires are always less than a few months old and free shipping. I also get the order in 2 days, every time.


Hopefully they will work on my rims. They are not GM rims, they are chrome 16 inch ambulance rims. The 235 mount on a 6.5 inch wide rim, which is what the factory rims would have been. The chrome rim might be a 7 inch or a 6.5 inch. I don't know what was used on ambulances in 1999. That is the year the rims were purchased.
