35" Tires on 2009 G-500
Just bought my 2009 G-500, and would like to replace to 35" tires. Got today 275/50-20" (app. 31"). Got some question though:
Would I need to lift the car?
Would changing to 35" tires, would really change the driving style? impact power?
I noticed gear ratio at the axles are 4.37:1, which should be low enough I think?
Does anyone have any experience with this?
Thank you for any info,




I'm going to lift mine a couple of inches max, and I'm thinking I can get maybe 33.6 inch tires on it (305/65R18 - I have the older G55 9.5 inch wide wheels) Pretty sure that would also require wheel spacers as well, for turning clearance.
Let me know how it turns out, I can't find much information on lift w/tire sizes for the G anywhere.

I also plan on lifting 2" only, got 20" rim, so looking at 275/60R20 (33"), might try also the 275/65R20 (34")




I'll let you know what setup I end up with next Spring, I have my eye on a 40mm lift with ORC or Thor springs and the 33.5 in tires mentioned. I'll probably have to do some experiments with just one wheel.
Then, if you still want to carry the spare, you have to worry about the rear door weight limit. These tires will be 15-20 lbs heavier.

Without the lift, I highly doubt there would be clearance with the larger tires. It's close as is. If you do decide to lift yours, strongly consider a sway bar. The only one I could find is made by ORC but I drove my G for a little bit without it on the freeway and there is an uncomfortable amount of body sway at higher speeds.

I have the same spare tire cover as well, any issues with the increased weight of the spare?

The VTS wheel cover, differential covers and transfer case cover came from www.g-wagenaccesories.com.
The H&R wheel spacers, brush guard grilles and black wheel center caps came from www.fourbyfourclub.com
The rear Brembo brakes came from www.racetechnologies.com (one of Brembo's US distributors) who sent me to Supreme Power Inc. (www.supremepower.com) for installation
The rock sliders, front & rear underride protection and turn signal guards came from GfG (Gesselschaft für Geländewagen) at www.gfg-shop.de/gb/
I got the tires from www.fourwheelparts.com and a few other random parts from ORC (Off-Road Center) at www.orc-shop.de/en/
In addition, I purchased some OEM items off eBay and other smaller more generic items off Amazon.
Www.gwagenparts.com has a wide selection of items but I never actually purchased anything from them. However, I have met with an employee of the company to look at my G and he was very helpful.
Let me know if you have any other questions!

Yours is very close to what I'll be doing to mine soon, I'll return to this thread and post up the before and after with some pics.

The rear Brembos are strictly to have more stopping power (larger calipers and bigger, two-piece discs). I only got the rears because Brembo doesn't make fronts small enough to fit my 18" rims although that may be changing soon.

If it wont do, I'll go down to 275X60X20, that is 33.1" tires Also, as I had Cooper MT tires, I had lots of noise in the car
Looks the way I like it,
I had to do most of it in my Jeep Wrangler with 5" lift. with the merc I plan only some soft offroading
What year is your car? I lost some engine power changing to the bigger tires

Just had 365mm Brembos put on the front. Brembo didn't make front brakes to fit the OEM 2010 rims so it took about 6 months for them to engineer it but they finally got it done. Supreme Power in Fullerton, CA installed them.
As for some of the other parts... The dust covers on the front two ORC/Bilstein shocks melted on to the cats. The turn signal guards and the rock sliders purchased from GfG have started to rust a little bit. A screw broke on one of the brush guard grilles but that's about it after many miles of on-road and off-road traveling since my last post.

Nice upgrade on the front brakes! How much of a braking improvement is it? I imagine the braided lines help some as well. So is this a one-off custom build, or does Brembo offer this size brakes that you can buy and adapt for the G?
Receiving some of my parts (shocks, springs, spacers) this week to get ready for my build here pretty soon. I'll probably start a new thread, though I don't think I'm doing anything you haven't done already.
