New here. I've been perusing the posts to try and find a definitive answer to my question, but haven't come across anything I feel confident about.

Ended up with nails in three of my tires... So, I'm having to replace the set. I have a 2023 Discovery HSE R-Dynamic with stock 22" wheels (I'm sure someone will tell me that I should replace my wheels with 20" or smaller, but that's not in the cards at this point). I'd like to get A/T tires, as I've had nothing but bad luck with the OEM Pirellis. Currently running 285/40R22.

I'd like to increase my tire size to the extent possible/reasonable, without needing to cut anything to prevent rubbing. This is a daily driver, but I'm also on construction sites frequently and at the ranch on occasion.

I'm considering installing either the 2" or 1.5" lift rods (Lucky8/Proud Rhino or Johnson Rods)--1.5" would be preferred over 2", unless the 2" will allow larger tires.

I like the Toyo Open Country A/T III tires. From my research, it sounds that the 285/45R22 will comfortably fit with the 1.5" lift and that the 275/50R22 MIGHT fit with the 2" lift.

Anyone have a similar set up? Anything else I should be considering? (Bonus points if you can tell me whether I can get a full size spare to fit and if I'm going to have any issues with the TPMS).

Thanks! I appreciate the help!

 

Rather than getting lift rods, consider getting a GAP IIDTool. It will allow you to set the normal/base ride height up or down from the stock height without any physical parts to change. I've got an unused set of Johnson rods because I got the GAP before I got around to installing them.

 

For anyone who comes across this in the future with the same question, here’s my update.

I ordered both the Proud Rhino 2-inch lift rods and the Johnson Rods 1.5-inch lift rods. In person, the rod sizes appear identical (see photo), so I’m not sure why the stated lift heights differ. I installed the Proud Rhino rods. The installation was very easy—I’m not a “car guy,” but fairly handy. You don’t need to remove the front tires if the vehicle is lifted into off-road height or if you jack the car up. You do need to remove the rear wheels. I used a golf divot repair tool to pop the clips as suggested in various posts. I didn’t take before/after height measurements to verify the exact lift.

I did quite a bit of research on tire sizes. This forum was extremely helpful, though there isn’t much information about fitment on OEM 22-inch wheels, which makes sense since most people run 20s for increased sidewall. Email guidance from Johnson Rods was that 275/45R22 would fit (or 275/55R20 if using 20-inch wheels). Email guidance from Lucky8/Proud Rhino recommended staying at or below 32 inches of overall tire diameter and at or below 11 inches of section width.

All-terrain options for 22-inch wheels that meet those guidelines are fairly limited. I was seriously considering the BFGoodrich Trail-Terrain T/A in 275/45R22, and everything I read suggested that it’s an excellent tire. I personally wanted something a little more aggressive. I ended up ordering 265/50R22 Goodyear Wrangler DuraTrac RT, hoping the narrower width would allow a slightly larger overall diameter. They fit perfectly. There is no rubbing at any suspension height. They are extremely close to the plastic vent/air guide at the front of the wheel well, but not touching. I have not had any TPMS issues with this setup. I also did not purchase a full-size spare with these tires, so I’m not sure whether a 265/50R22 will fit in the spare compartment.

The team at Discount Tire (Dallas/NW Highway) was fantastic. They let me order the tires, test fit them for free, and were willing to order something else if they didn’t fit. Honestly, the guys at the shop and I did not think they would fit when we first saw them.

Here are the size comparisons that I considered. The OEM 285/40R22 tire looks too small once the vehicle is lifted. The 275/45R22 size will fit; its overall diameter is about 31.74 inches and its width is about 10.83 inches. This is only about 0.17 inches smaller in diameter than the popular 275/55R20 size that many people run, which measures about 31.91 inches. The 265/50R22 tires that worked for me measure about 32.43 inches in diameter and about 10.43 inches in width, which makes them roughly 0.69 inches taller than 275/45R22 and about 0.4 inches narrower. Based on everything I’ve seen, I do not think that 275/50R22 (which is approximately 32.82 inches tall and 10.83 inches wide) would fit without trimming or cutting inside the wheel well. I originally thought that 285/45R22 might also fit, but I’m less confident about that size after seeing how close things already are; the added width is probably where clearance issues would show up. Maybe someone will try and report back.
