I just picked up a set of LR (72189) 18" wheels today and already have a set of Rhino rods. Been doing a lot of reading on tires and would like to mount some 265/70/18s on these. They would come in at 32.6" so another 0.5" over most 275/65/18 (32.1") setups (Duratracs, etc).

My thought was to eliminate rubbing issue ppl see with 275s and even stuffing 285s in. I may nullify the decrease in width with the increase in diameter however. So any input is welcomed (pics, thoughts, experiences, etc). Thanks in advance.

I looking at some Grabber AT 2 (265/70/R18 124/121R) tires atm and am willing to entertain other brands/models.

BTW: My 19" LR 72207 wheels are for sale with a 72191 19" wheel for spare. The spare is free so you can eliminate you donut steelie.

 

Not sure but my hunch is that your trade-off (width for diameter) may be okay with clearing the frame rail and the wire bundle if you've moved it (driver's side wheel well) but in the rear you will likely rub in the rear wheel wells in the FWD section.

 

I went with 265 60 r18's because that size is more widely available if I need to replace tires while travelling. I would also be very interested to know if the 70's are workable, I do sometimes wish I had more sidewall.

 

Thanks for the reply. I was thinking the same thing after seeing some pics of the 32.1" setups. Anyone one with this setup care to measure and comment the distance/gap of the rear front wheel well?

 

I have that setup; however, right now I have the 19s with my winter tires mounted so I can't go out to the garage and measure for you, sorry man. Here is a pic though, that shows how close it can be. The tire is drooping in this photo but you can see the potential for interference.

 

I'm running 275/70-18s currently; Previously 275/65-18s. I don't forsee any special problems with 265/70s beyond the typical mods-

front of rear wheel wells - plastic will rub. If you don't have rear hvac you can pull the inner fender and simply fold over the body seam here then heat the plastic until soft and form squish it down for clearance. If you do have rear hvac there are 2 aluminum coolant lines here that either need to be re-routed into the channel along the edge of the wheel well or simply replaced with 5/8" heater hose and again routed into the open channel.

outside of frame rail, drivers side front - there's a wiring harness along the rear exposed section of frame that's at risk of being snagged by a tire at full lock. Just zip-tie it up to the top of the frame and out of harm's way

bottom/rear of of front wheel wells - the frame horns extend into the wheel well and are a common rub point when turning. Early trucks have these bolted on and can simply be removed while later are welded. They can be cut back and a flat plate welded on to improve clearance. It's a fairly easy job.

You may get some rubbing in the inner front fender liners, but they can be easily trimmed as needed.

I haven't tried your specific tire size, but these are the common rub-points. It seems to vary slightly among vehicles and exact tire models as for what will and won't rub. Some people report size xxx fits fine with no rubbing while others say they had to cut to run the same tire, so YMMV.

In general I recommend the 265/65-18 as the easy go-to tire size for most people. Your a bit taller but should have no major issues.
