Which ones are you going with?

 

[JDLouisville]

Likely the KO2s.

Milestar Patagonia 37x12.5x17 72lbs

Likely the KO2s.

I’ve been really happy with KO2s. I’ve never run them in 37, but I had 35s on my JK, and I’ve got 32s on my current rig (2017 Tacoma). They are not the right tire if you are in mud frequently, but they are pretty good at everything else. Good in the rocks, and great for fast driving on dirt roads / desert. Great on slick rock (when it’s dry). Strong side walls - though I run E-rated tires, so maybe the C-rates ones aren’t as burly. KO2s are better on road - with a higher certified speed limit - than any MT I know of. You don’t see them in 37 that often, because usually someone who goes up to 37 wants an MT, but I think it’s a good choice. Unless you are upgrading axles, ball joints, and other running gear, watching tire weight is smart. Oh yeah, KO2s are also decent in snow. I run dedicated winter tires, but I like having KOs because if we get an early storm like we did in September (18 inches at my house), I’m good to go. MTs are good in deep snow off-road, but are terrible on road when it’s really cold/icy/snowy.

Thanks for posting this! That’s some good community service.

This is a very popular choice... I think the lightest MT.

I’m curious, my falken wildpeak ATs in 285/75r17 are 65.5 pounds. The discover listed above in 37 is only 68 lbs, which is only a 2.5 difference per tire.

Is it the weight of larger tires that require a gear change? If so, it’s really seems nominal. The stock rubicon falkens are right at 59 lbs. I just find it hard to see how 40 lbs of tires (when a rubi owner upgrades to 37s) around the whole vehicle means it needs a several thousand dollar gear change. Someone please enlighten me?

How do you like them TJ? Seems resonablly priced? Pros and Cons?

I am still running the 35" Patagonias I took off the JK before I traded it in on the JTR. I like them. They do well off road and in the sand dunes aired down. For some reason they are a lot louder on the Gladiator. When they were on the JK 2dr, I could barely hear them. Admittedly, I bought them for the JK because they were very inexpensive.
When they wear out, I will be shopping for 37's. I will probably get another set. I really like the Ridge Grapplers, but they are pretty heavy.

Re-gearing compensates for a taller tire by restoring the intended factory gear ratios. It is the height of the tire that is the key factor (not the weight). However, taller tires are also usually heavier, and added weight in the tires/wheels requires additional torque to get moving, and additional braking power to bring to a stop. In addition, heavier tires/wheels stress other elements in the suspension and steering, like axles, ball joints, tie rod ends, etc. In summary: going to a significantly taller tire creates two different sets of problems: the height of the tire changes the factory gear ratios (requiring a re-gear to restore power), and a heavier tire places greater stress on steering & suspension components (requiring some upgrades - depending on specific circumstances).

Do you have to re-gear? Depends on where you live, how you drive, and what your expectations are when you press down on the skinny pedal.

If you buy a Gladiator Rubicon 3.6 Pentastar (with 4:10s), and go from a 33 to a 37 tire, but you live at sea level, and you live somewhere flat, and you are not trying to drag race people at stop lights, and you bought the 8-speed auto, you probably don't need to re-gear.

If you buy a Gladiator Rubicon 3.6 Pentastar (with 4:10s), and go to the same 37s, but you live at elevation, regularly drive over 10,000 foot passes and commute up and down a Canyon that involves 3,000 feet elevation loss/gain, and you bought the 6-speed manual, you will likely be dissatisfied with the vehicle's performance and will be desperate for a re-gear. Or a Hemi swap. Or a supercharger. Or all three

I can't vouch for where that info came from, but I do know that there is a lot of bad data and erroneous data in the spec sheets you find online. If there is a particular tire somebody is truly interested in, I'd suggest checking multiple sources for the weights to make sure it all jives. I've even seen some bad numbers in manufacturers' own listings on their sites.

If you can’t trust the manufacturer then why would we trust anyone else numbers? No company weighs every tire that comes off the line and reports each individual weight to the consumer. There’s an average taken from sample Parts per 1000 or even parts Per million.
Safer to what manufactures specs...The engineer in me assumes that these numbers = weight +/- 2 or 3lbs. I have 4 Falkens they were all with in 2lbs of each other. It’s a guide line not bible.

@WXman you get another Jeep or you just stopping by for some ice tea

I put the new Geolanders on my super scientific Cal-Tech bathroom scale.
The heaviest one came in at 77.4 pounds for 37/12.5-17 the lightest was 76.9 Close enough for government work!

Spot on! I live in N.E. Ohio, we have hills, not mountains, and we are approximately 1100ft above sea level and the 4:10 auto with 37” tires is ok for DD use. May not be great for heavy towing but fuel mileage recovery will be hard to financially justify through regearing. That said, I want to but may not need to go to 4:88
In my auto Rubicon.
