I am looking at getting a set of 37" Toyo tires for my 07 2dr. in the 37x13.5x17 size they only come in Load range E. I am wondering if anyone can comment on well they flex. I have the 40" Toyos on my JKU and the tire flex is great on the rocks but they are load range D, but I am worried the stiffer tire on the lighter jeep might lead to a bumpier ride on the rocks than I am looking for. Any comments or experience with the 37s is appreciated.

Sorry I started laughing a bit when I read this. After you air down to 10-12psi on a rock trail the load rating of the tire is not really going to impact anything to do with your ride quality. The huge rocks you are going to be going over are going to have a much greater impact on your ride quality then the load rating of your tires. The only thing the heavier sidewall on the rocks is going to do is help you not tear a sidewall a bit better then a lighter tire.

When people comment on ride quality issues regarding E load rated tires they mean in reference to higher speeds with higher tire pressures. To combat that a bit run your new tires a bit lower on air then you normally would for general use around town for a week and that will break in the tire sidewalls a bit nicer to give a little nicer ride when at proper pressure on road.

 

That is good to know.. I have seen people complain that a load range E tire aired down will still look and act like it is aired up and not really conform to the rocks very well. I think I am still going with this tire, just wanted some feedback from others.

Something in general to keep in mind is typically the larger the tire the lower the pressure you are going to run for normal use even. A tire the size you are talking on a jeep, depending on how heavy your rig is will probably wind up being in the 23 to 25psi range for everyday use even.

Another thing to consider when talking about on/off road performance compromise is the size of the wheel you are mounting your tires on. Smaller wheels off road will give you a larger sidewall and conform a little better when air'd down, while at the same time reducing highway manners. As the wheel size increases that starts to shift in the other direction. I see you mentioned a 17 inch wheel. That is a very nice wheel size for 37s for all around performance I think. Should be a great setup although my personal preference is for narrow tires for my use.

 

While it will be stiffer, it will also be more durable. You need to decide which is more important to you. I went with durable

 

Have them. Run them at 8-10 off road, 28 psi on road. Work great and very tough.

 

This tire specs at 14.6" wide. Any issues with the width on road or off?

 

Pro Comp 17x9 w/ 4.5 BS and 37x13.5 Toyos I touch the LCA and Frame rails at full turn. It is not noticeable when driving, but I have to touch up the paint a few times a year.

 

You will love the Toyos, I have a buddy with a 12' two door on a 37" Toyos and couldnt be happier. It rides great, handles excellent and performs offroad perfect.

Just my two cents.
