Hi everyone,

today im picking up my new lariat 5.0 with 20" wheels and 3.73 gears , and im wondering would it rub if i put on it 2.5 rc leveling kit along with 33" bfg ko2's. And i dont want to do any cutting , I'd really appreciate the help, thank you.

 

You should be fine with that setup. I have 20" stock wheels with 34.5" tires and 1.5" level. It did not rub.

 

thanks really appreciate the advice. I will be sharing pictures onece i drive it off the lot.

 

Congrats! I hope you enjoy it.

 

If you are planning on keeping the stock wheels check out this thread:

Another good thread that might have aftermarket wheels and OEM is the following:

I don't believe you will have any issues with height from what I have read, but if you use an aggressive offset, a really wide tire, or wheel spacers (or some mixture of these) you could have some issues. I would hope (and don't think) you will have to cut the crash bars, but maybe you would have to bend them out a bit.

Congrats and good luck!

 

This is true. With the setup I described above, I did not have any rubbing issues..... until I later added wheel spacers. Had to spread out the crash bars a little.

 

Do you know how wide i can go ? And thanks.

 

I haven't made a change over yet myself, but I have been eyeing some similar sized tires as you might be. If you are trying to go a roughly 33" tire I would assume that you might be looking at doing the 2 inch level like you mentioned and using these different tire sizes on BFG K02 that I have looked at.

305/65R18 (33.5"x12.2") - I have really been thinking about this size especially. I think the smaller rim size will make ride quality decent, be somewhat more aggressive, and with aftermarket rims I think I can shed about 6 pounds of weight per wheel than if I tried a bigger size on my 20" sport rims which is important with my 3.31 gear ratio. Not to mention I think that it would be manageable to not do an speedo recalibration that might get you in trouble with warranties. I might only be concerned about how close the tire will be to the upper control arms and the only way to fix that is with spacers which could lead to issues with rubbing the crash bars.

275/60R20 (32.9"x11") - Might be a good compromise if you are trying to get a little bigger tire without much trouble. However, it won't look nearly as aggressive and is D rated (matters if you really want E rated).

275/65R20 (34"x11") - A fairly popular tire here and might be more advantageous cost wise compared to bigger tires. Getting into the realm of possibly needing speedo recalibration. However, I think the next size I mention has it beat for ride quality.

285/65R20 (34.5"x11.5") - I would seriously take a look at this size if you are looking to keep it on 20" wheels. You would still have to be careful as to what the offset of your wheels might be as it could get you in trouble. Same deal if you are looking at spacers. Also you might need speedo recalibration. It is a somewhat popular tire on here so I am sure you could find some good examples and be safe.

305/55R20 (33.2"x12.4") - This might have some of the similar benefits and issues as the 305/65R18, but would fit the 20 inch wheel. Might be more prone to rubbing given that it is a little wider.

I mentioned so many different tires because to be entirely honest I haven't even made my mind up yet as I am trying to wear down the original tires and pay down my loan some more before I bite the bullet. I think any time you are looking at going over 12 inches wide or having an aggressive offset you are going to be getting really close to rubbing either the upper control arms or the crash bars.

Hope this helps!

 

Thank you so much, I really appreciate the detailed feedback. You really have layed down all the info i could use. Here is a pic of my truck fresh of the lot. I hope next time i share pictures will be with the new set up.
