Largest Functional Tire Without Mods

[C-Mack]

Mostly likely a question that will get a lot of “Why would you want do that?” comments but has anyone fitted 285/65 on the stock 18” alloys? I would like a little more width and a touch more sidewall height as I think this size works out to around 32.6” tire which is ideal for me as I’m not looking for supersized balloon tires or end up with the Tonka toy truck look. I plan on keeping the vehicle suspension stock and down the road may entertain a second set of 17” aftermarket wheels for off-road duty but I’m open to other suggestions.

… wanting to vet out cost of upgraded clutch packs and tune the only thing we could find was that the clutch packs are the beefed up ones

How was this determination made? Did you examine them directly? Is it a ZF or BMW part number, or other?

Called and ask for a kit.

oh that is great then, Dumb question number two does the MT 255/85/17 fit on the stock steel wheels and still work or do I need to buy a set of OWL wheels?

No need to purchase new wheels. I just had them installed on my truck and they look great on stockn17” steel wheels. I’ll post a pic. They are also not any louder than the BF Goodrich’s. I am sure my gas mileage will suffer. Truck looks so much better! The proportions are right now!

Hello ladies,

Anyone know what the largest tire size is that can be used without rubbing, binding, and without cutting the vehicle to make it fit?

I'm also wondering if there are any options out there for upper control arm replacement to properly lift the truck say... 4 inches, while retaining correct angles.

Lastly... I see that spare tire upgrade size will likely be limited by the left rear access door needing room to open before the right side... looks like about 2 inches further would be the max...?

I just been through this exercise. I would say that Mickey Thompson 255/85/17 A/T tires are the largest without a lift. I did not want to lift my truck because of the issues with the drive shaft, thus, I went with these. The tire is actually 34.6” which some say is taller than typical 35” tires. The width is around 10” which is less than a 285/75/17. I’m told that these do rub because of the extra 2.5”’s. I am very happy with these …
I did purchase a relocation bracket from Owl in order for the rear door to open. I did have to purchase three 14m x 1.5 50mm bolts as the ones in n the kit do not allow you to mount the tire in reverse. I wanted to keep the original tire cover , thus, the reason for the longer bolts. The ones supplied are too short.

That is awesome thank you for posting!!!! That is exactly what I want to get accomplished.

Good morning,
I guess at the end of the end it’s all a matter of preference. I have a set of 285/65/18 on my DISCO II and it looks great! Proportions are spot on. On my Grenadier I always felt that the stock size didn’t look right. I wish the truck would have come with a little larger tire, however, I understand that they were probably concerned with gas mileage and availability concerns world wide with bigger tires, thus, choose a common size that is readily available. I too was a little concerned about going too big or lifting the car, thus, I went with 255/85/17’s. These tires are slightly thinner than the original. They are about 10”, thus fit inside the wheel well. They are a 34.6 in height and I feel make the truck look much better proportionately speaking while not having the tires stick out of the wells. These fit without any lift and do not rub at all even when fully articulated.

Here are the MT 255/85r17 on Owl Sixty wheels w/stock suspension. View attachment 7882450

Looks awesome!

 

[John Acosta]

Fantastic. I really want the 255/85 but not particularly drawn to the Mickey tread pattern. Have you driven them in mud?

No, I particularly went with MT because min snow up in big bear and was told these work better than BFG’s. I’ll probably find out soon. Although personally I don’t mind the aggressive thread pattern. I also wanted a 10 “ tire.

33x12.5 R18 with Black Rhino wheels.
No rubbing at all. No lift.

Great option too! Are your lights tinted yellow or are they aftermarket lights?

Looks like you are in Pasadena as well and maybe an home in Big Bear. Our second home is in Lake Arrowhead. Are cars are twins including the tires. Let’s hit the trails!
