I've got some Yokohama Geolander ATS tires on my RR on the standard rims. The tires are 235 width.

What's the largest size tire I can put on the standard rims before I start having to worry about arch clearance, or axle articulation interference?

Thanks,
James

I would check the main site they have lots of sizes and user feedback. If you want larger tires I would do what it takes to fit 33s, but thats just me.

You can I believe safely use 225/75R16 or 215/85R16 without a lift, provided that your springs and shocks are in good shape. 235/70R16 should also be okay. 235/85 or 245/75 will probably require some lift and/or trimming. 265/75 definitely requires a substantial lift and trimming and adjustment of bump stops. Anything taller than stock effectively gears you up and arguably the RRC is overgeared from stock. I have 215/85R16 tires on mine ('92 3.9-liter) and I find it significantly overgeared. I don't find it a problem except when descending steep grades off-road, where as I say it was already overgeared with stock diameter tires. I'd love to go to taller tires (probably 235/85) but feel that I'd have to either go to lower ratio diffs (4.10) or stop going down steep trails. Another factor to ponder when considering taller tires and/or lower gears is that the axle components are already marginal in strength. Upgrading the rear axle isn't too costly but the front can get very pricey.

You may also consider 245/70-16s. I dont know about the RRC rear rubbing issues, but my experience with Disco 1s, 245/70s or 225/75-16s were the largest you could fit without rubbing. You can get a heavier duty tire in the 225/75-16 size.

235/70/16 are a direct replacement for the OEM 205 section tyres without any rubbing or modification issues as the rolling radius is the same the speedo will also remain accurate.

If you go larger than 235/70/16 you will need to adjust the steering stops to avoid rubbing. Significantly larger tyres will require body trimming as is documented elswhere on this web site.
