So i'm looking to possibly go to a 37 inch tire on my 2018 Scab. Was gonna start with the SVC CAS system to level it out since i've read quite a few good comments. My question, I have the black beadlock capable wheels and not looking to fork out any cash on new wheels at the moment. Can I put a 37 inch tire (somehting like a KO2) on my current "OEM" Wheels. And if so, does that help with any possible rubbing that might of occurred with different wheels? And would you suggest new deavers for someone that really isn't gonna be pushing the truck in the woods or desert. This is my daily driver and i don't wheel other than backroad driving to fishing and biking spots. Just wanted a bigger tire. What would be my optimal setup for adding 37's to a truck that isn't really gonna be pushed to its actual capabilities any time soon if at all.

side note(if you can't tell by the questions)...i'm not very mechanically inclined so be as exact and as harsh as you feel you need to be...

I've always had Wranglers prior to my raptor with one stop off in a Hummer H3T(the pickup version of the H3)...The raptor has always been my dream vehicle and i finally was able to get one this year after getting a great trade in price on my last Wrangler. I do have the MPT tune currently on the truck and hope to add an upgraded intercooler soon.

Also if there is anyone in the Western Ohio area that knows of a shop that they would trust to work on a Raptor, i would appreciate any contacts.

Yes you can put 37 on your factory wheels. It’s not advised because you should have at least a 9inch wide wheel stock is 8.5. I went with a 17x9 with a 0 offset and very minor trimming and 37/12.5/17 fit with no rubbing. If I do any major off-roading I’m sure they will rub and may need to trim more for that. Also now my stance is wider so my truck can’t go through a car wash.

If your going give advise, at least know what your talking about. You say you can put 37s on the factory wheel but it's not advised because of the width of the wheel. 37 is the tire height not width so the width of the wheel has no factor here. If we assume that your talking about mounting a 37x12.50r17 onto the stock 17x8.5 wheel, there are still things wrong with your statement. You state that it's not advised because you should have at least a 9" wide wheel. Not advised by who? What source did you get this from? Was this from a tire manufacturer? Did a local tire shop tell you this? Did you just make it up?

Either way it's wrong. 37x12.50r17 tires vary in width between manufacturers but are generally between 12.4" and 12.8" wide (the stock 315/70r17 is also 12.4" wide). Most tire manufacturers measure the tire on a 9" or 10" wheel and recommend they be used on a 8.5" to 11" wide wheel. That said not only is it okay to mount a 37x12.50r17 tire on the stock 17x8.5 wheel, many trucks running competitively in off road racing run a 37x12.50r17 on a 17x8.5 wheel. I'm currently running a General Grabber X3 37x12.50r17 mounted in the stock forged wheel. I am running the ICON AAC set at 2.25" in the front and Deaver +3HDs in the rear and they clear with no trimming. I will need to trim before doing anything more aggressive than a washed out gravel road but they currently have about 1/2 clearance from the inner liner with the wheel turned to the closest point.

I was told
that you need at least a 9 inch wide wheel. They say you can put them on a 8.5 wheel but they don’t advise it. That’s from discount tire. So why do you have to bash people on this. Does that make you feel like a big man? And if someone was given the wrong advise then why not just correct them instead of bashing them. That’s what I was told by discount and another local tire shop

Your information was wrong so I corrected you. If you had listed the source in your post, my response might have been different but you didn't. You didn't offer an opinion or relay that Discount Tire had advised against it. You gave advise as a statement of fact. As I stated if your going to give advise, you need to know what your talking about. Otherwise, state that your offering a opinion or relay where your information is from. Call it bashing if you want but offering incorrect information is far worse than offering none.

It sounds like DT gave you some bad advice. There are MANY of us on this forum running 37s on 8.5" wheels with various offsets. I have had mine on 17x8.5s with a +6mm offset for over a year without a single problem.

By the way, this post was over a year old when you first replied to it...

Like I said I was told and I also didn’t say you couldn’t. And I’m sure you’ve never been wrong before or given wrong advise. So I’m sorry I stated something I was told I’ll make sure to never say anything wrong again ok mr perfect
