37/38" ride quality vs stock tires

[airtime]

wanting to get an idea of the ride difference between a stock 80 lc with stock suspension vs 33" tires, 35" tires and 37/38" tires. this would be for on pavement driving, as in dailly driver. also throw in the off road qulities of the tire. i know lift will play a part in it but we can see it in your signature. let the info roll

This:

To this:

is a big evolution and hard to quantify as most of us did not do the transition in one single step. There is a vast difference between the same rig running a mall biased street tyre when compared to the same size off road tyre. The 37" Iroks on mine are not even balanced...

My boggers aren't smooth, 38.5. Could be warped steelies, could be too many golf balls, could be an out of round tire. Going to try having them pad balanced ($$$) and see where that gets me. When I don't have the terrible steering shimmy/shake it feels kinda smooth though. 30psi in 38.5x11r16 Boggers, Bias of course.

If you still plan on driving long distances or just DD with near stock handling stick with 33"s. Invest in a OME str.stblzr because the wider the tire, the more it tends to want to follow the groves in the road

Not true at all. I ran my 36 radial Iroks 3500 miles anywhere between 75-85 mph to the 50th in Torrance. Setup correctly you won't be bothered by it. The added lift and tire hight takes a quick getting use to but not a problem. Mine runs just as good as it did on 33s. I cannot stress enough how important it is to do things correctly, taking short cuts to save money is not for an 80 series.

Take the extra time (and money) to ride match the tires to the wheels, have a latteral balance done and put in dyna beads for static balance. Your Irok radials will ride like glass.

Yea they may ride nice smoothish but nothing like stock. I recently drove my 80 to arizona with 37 swamper radials. on the way back i swaped in some 0e new fj cruiser wheels and tires. I had forgotten how smooth an 80 can be

 

[FJnAK]

huge difference between Swampers and stock tires, mine stock with 285's rode good.

With 37" bias Iroks it has a bit more vibrations, the tires don't balance out all the way. I'm going to try dyna beads next.

When I put my 315 All Terrains back on it rides very smooth again.

But for the record I daily drove it all summer with the 37's and it wasn't bad. When I get the 5.29 gears it will be fun to drive with the 37's on and I may try out the IROKs in the snow this winter.

I have 37" radial Iroks balanced with dynobeads. I know for a fact I have an out of round tire in my back right which causes a slight vibration at all speeds (could also be mud in there, not sure).

37s ATs would be like glass. MTR vs. AT vs. HT is the main factor here. Balancing them is the next.

If you are looking for a comparison of stock HT vs. 37" MT you are not going to like what you hear.

Now...as for offroad performance? 33s will get you most places. 35s will get you to more. 37s will get you everywhere else you need to go on stock running gear (and will likely encourage you to break and dent a lot of stuff). 37s caused me to do more mods to the axles, suspension, etc than anything else I did to the truck, it is a veritable money pit mod.

Hope this helps!

 

[airtime]

well, as far as stock ride goes, are we talking about cadilac ride quality to begin with or 1/2 ton 2-wheel drive chevy truck?


also, fjnak, what lift are you running? any rubbing?

i see most of you are still running your flares, any rubbing? how much axle articulation are yaw getting?

would yaw daily drive yaws 80 with 37" tires? i have a 11 mile trip to take the kids to school, one way of course so gas will not be that big a difference from my current gas guzzling 1/2 cevy truck (12 mpg).

thanks for the info guys.

-Dusty, you also bought your tires second hand if my memory serves correctly. There is a HUGE difference when you take a new tire and ride match it. Also the SSR radials from my research is on the bottom of the popular swamper list for numerous reasons.

Also Dyna beads will not solve a latteral inbalance. If you doubt the soomth ride of my tires I invite anyone to take a ride.

-FJnAK, there is no compairing a bias ply tire to the ride of a radial -- I've been there tried that.

My true test was when my mother took a ride to church. She's stricly a Cadillac driver who will pick out and make know any uncomfortable ride but she still made the comment that my truck didn't ride any different than it did before the higher lift and tires.

I DD my radials 50 miles a day. They are smooth for a 37, but obviously not the same as running a highway tire. Especially when you get above 80mph, if you do. I have mine balanced with equal. It pretty much comes down to your luck with balancing them. Not many people DD tires that big so not many have experience with it.

 

[FJnAK]

Bear80, I know that Bias cannot be compared to Radial Iroks, but Bias has a better side wall and I bought mine mainly for off road wheeling. They do ride better than my 38.5 TSL SX bias Swampers though. Iroks seem to be a better made tire, at least they are more round.
It is hard to compare the tires though, stock tires don't grab the ruts in the road, wider 35's and 37's do.

What all this comes down to is what are you planning to do with your cruiser? I'm running 37" Iroks because I bought the rig to replace my spring over V8 FJ40 that had 38's and was off road only. I wheel it alot and on muddy trials and want to drive more than I winch. It still hauls my family every day just fine.

I thought it's pretty more related to a tire than size .. Irocks and SS in general are perfect off road tires .. but not designed for on road use at all ..

If you go with 37" MTR or Toyo something like .. you will notice no real problem on it .. just my feeling it's the steering more " streesed " maybe ..

 

[Bear80]

The fact is ANY super aggressive MT tire will not ride like a highway or mild AT tire, no matter the size. Going up in sidewall does not significantly affect the balance or ride quality. The wider a tire is the great chance for LATTERAL imbalance. As Tapage said, the build quailty of the tire is also a huge factor in ride quality. Swampers are not know to be great highway tires but I think the Iroks have had more time put into them to make a streetable tire.

My truck would make a fine DD but for obvious reasons plain silly.

 

[airtime]

so for aggressive off road 37" range tires, iroc seem to be a popular choice here. how do they pull in mud? i realize that they are not going to pull like a bogger but i would guess they would pull more than a radial at tire or bfg mudder or equal.

bogger being a 10 what would you rate the iroc?

iroc compared to a trxus?

i would not mind sacrificing on road comfort for a better off road tire as long as the mud tire was vastly superior off road than the better riding tire.

 

[Bear80]

That was just covered in another thread probably not even a week old.

 

[airtime]

i'll do a quick search then, but my previous searches on tires have been slim. most of what i have learned is from reading other off topic threads about suspension.

 

[airtime]

search of iroc mud tires return 3 results, one of them this thread, the other two back in 2004.

 

[LC80Ducati996]

Look at the 325 coopers, 37x12.50x16 only in maxxis stuff, on a 17 wheel plenty of options in 37 round and 12.5-13.5 tires.

Hankook RT Muds are pretty quiet and long wearing so are toyo open muds.

Something like that just fine. IMHO a 24" bogger would be loud on the highway just like a 44"

bogger + irok.......that was hard
