New tire and wheel

[Frank L]

I am looking at this set of wheels and tires to mount up to a 2013 screw. I know I need to go to mid perch. Aside from that I don't know what will fit and what won't. 37x12.5 or 37x13.5?? I want a 37" tire and a 20" wheel. I go off-road 4-5x per year but nothing crazy I'm not into beating or jumping it.

Any comments or concerns...

Thank you in advance.

Here are the 2 sets that I'm looking at

There's quite a few threads thoroughly discussing this topic.

Yes and I went through most of them without gaining much knowledge. Some say this some say that. Thanks for not helping.

This is the tire and wheel section... :d

Good info at this link

Some good info here on changing wheel size, offset and backspacing considerations.

search is your friend...but, you'll need to consider a few things. is it a true 37" tire? do you plan on fully compressing the shock on a jump or offroad? you'll have to hammer in the pinch welds to avoid rubbing for sure. if you get a more negative offset wheel, you're bound to rub and will need to trim. you're also going to lose power and will need a tune or regearing...MTs, like the toyo MT is heavy. you'll also get a lot of wear on front end components. your speedo will need recalibration etc. when you go this route, theres a lot to consider and sometimes it can open up pandora's box...

Thank you. I have a programmer that will recalibrate the speedo. I also have a Hennessy custom tune and cold air intake. The power at the flywheel is just sub 500

What tire are you thinking about going with?

 

[SlimChaChi]

just saw the offset and the tire, those tires i believe are true 37s and pretty aggressive. the offset is going to give you headaches.

I'm not running 37's, but I read quite a bit about it on this forum while I was considering it. Most people seem to like a +18 or +20 offset when running 37's since it should require less trimming.
