Show off your Cooper ST Maxx

Thank you I have looked at this a few times. I will say there is a difference once the tires are on aired up and and the weight of the truck is bearing down on them. I so far from what I have read and seen am intrigued by the 255/85 maxx. I just don't want it to be a bicycle tire compared to what I already have

 

Lose traction? On what....? Skinnies have the advantage in certain situations. Plus, tall 255's look badass.

 

Not really expecting to lose that much traction and spin out just because the road is a little wet and I have 255/85 tires. I'm not being that ridiculous. However a 265/75 is wider than a 255/85. Soooo that does mean more rubber on the road given a similar psi. Correct? I am wondering visually how different in appearance are they. Like i said I don't want bike tires on my truck but if they look damn close to the 265's I have now I am going to seriously consider these because I have been pretty impressed with them from what I have read.

 

And more rubber on the road means less contact pressure. Not good for ice or light snow, or mpg. Debatable for trail conditions. If you want to 'float' over something - deep mud, snow, sand - then you want fatties.

*I'm no expert.

 

My 255s do great in the sand, that's a real test.




Snow and sand mix.. no problemo

 

What's the specs on your rig?

 

Yea I have posted that, DoorDing might have also not sure. I had already bought mine by the time I saw the video, just made me even happier with my purchase.

 

Anything in peticular? My tire size is 255/80/17. Everything else is in my build https://www.tacomaworld.com/threads/chuxs-2013-beach-buggy-build.339950/#post-9024055

 

Alright guys, I got something to ask. I posted in the 255/85r16 Experience thread as well.

For those of you with 255/85r16 (and maybe 255/80r17) in the ST Maxx, does y'alls truck feel floaty, like the ass end is loose? I just got mine yesterday morning, but 75 mph on the interstate makes me feel really uneasy when I'm turning or changing lanes. I started with the tire pressure at 40 F/R, but then dropped them to 36/34 F/R, and that seemed to help it out a little, but it's still very pronounced. Have y'all experienced this, and did you figure out some way to minimize it/ get rid of it?

The tires ride great, and look great too, but this is kinda freaky. I read about people experiencing it on forums for 3/4 ton trucks that are heavy as heck, but I didn't read anything about it on here, and wasn't expecting it.

 

Took em wheeling over Labor Day. Impressed with them as always!

 

Not st maxx but I just went from 265 to 255 and they look the same.

 

Thank you

 

That looks pretty packed, I'd drive a rental corolla on that, like I did in WA state! Lol the said down here is loose and dry.

 

Hah that's just morning fresh tracks, two wheel anything will definitely get stuck. Just tried to grab a good picture of the tires. Being minutes from the beach I drive on a lot. The sand here in Jersey is always changing.. mornings can have dew in the air that makes the sand moist and clogs the treads turning all tires into slicks and making it easy to get stuck even in four wheel if you don't know what your doing, after a few hours of warm sun the sand dries out and allows the maxxs to crawl through the soft sand with the best of them. Hotter days during the summer I air down to 20 psi, this also allows the side walls of the maxxs to get in on the action. Aired down and low gear gets my truck through every deep rut on the beach. Come winter when the sand is colder I don't bother airing down and stay in four high. I am very happy with the tires performance in all scenarios and conditions I have come across on and off road, even in 255s. Just trying to spread the good word.

 

Unfortunately, there is a widespread misconception about wider tires. The fact of the matter is that the majority of tire surface area on the ground comes from length (read circumference), not width. You will get better traction from a 255/85 than a 265/75 in all cases except for very loose sand/snow/dirt that is so loose that it swallows your axles.

When you air down, you get better surface area from tall skinny tires than you do from short fat tires. Do some research and you shall find this to be true. The aired-down footprint of tall skinny tires is unbeatable in all conditions except for the most rare (those that involve surfaces so loose that they swallow your axles!)

 

This is a case of road wander. It happens because you have not adjusted alignment after you have increased the circumference of your tires. At the very least, get an alignment. To really goes balls out, get new UCAs and an alignment.

 

'Tis not the problem my friend. I have Light Racing UCAs and 2.9 degrees of caster on both sides.

 

Hmmm.. what exactly are your symptoms again?..

 

Installed them a couple days ago and I really like them so far.

 

When you're driving down the road, and you change lanes, or start into a long sweeping curve, the back end feels "squirrelly," as in it feels like the sidewalls are rolling over. Imagine what it would feel like to have a small amount of rear steering in a vehicle. I swear that is what it feels like. It sounds crazy. I do know that everything in the rear is tight, and I didn't experience anything like this until I mounted these up. I just went out and dropped the fronts down to 35 psi, and the rears to 32. There was some tread you could tell wasn't making contact with the roadway.
