Hey everyone, I hope I am not asking something that has been over and over 1,000 times, but I am still pretty new here and I just got my 35's installed. I do have minor rubbing but I am not worried about that in the least bit. What does concern me a little is the change in the ride of my truck. I really couldn't tell a diff. between my 325/60/18's and my stockers. But these 35's feel completely different. It is not that they are rough just cruising down the road...No, they are very smooth then. But when I hit a pot hole, or a set of rail road tracks, or any significant bump at a speed above 30 or so (the faster the worse it is I think), it feels horrible. I don't really know how to explain it, you just know it in the steering wheel, and by the sound. I am hoping others have this issue, and that it really isn't a big deal, just the affects of stretching and changing the angle of all the front end stuff with the bigger tire.?.?

 

im thinking your shocks may be causing that hollow/bouncing sound/feeling. just a thought.

 

Check your air pressure. Lots of times tire places air the tires up to seat the beads and don't adjust the pressure back down. I'd start there. With larger tires, I'm not sure you'd use 35 psi, but maybe 32 psi. These larger tires usually have a higher weight capacity and don't need quite as much air as the stock tires. It's all relative.

 

I think it is your leveling kit with 35s. Your suspension travel is closer to maxed out with a leveling kit, so when you hit dips and potholes you have less travel (I believe).

I have a 6" lift with proper differential drop and replacement shocks. The 35s hit bumps/potholes much smoother than stock. Driving offroad is far better as well.

My tire pressure is 32 psi if I remember correctly.

 

I agree about the chance of them being over inflated, I would look into that first. On a side note (sorry if you already know this) the sidewall (general construction) of an M/T is often "stiffer". Your load range is prob a D if not an E. Not sure what your old tires were but your new tires will not provide a whole lot of cushion to aid the suspension. Especially if they are over inflated.

 

Well, the tires have a 65psi max and there is like 50 in em now...I can see where that could cause a rougher ride, but I think I ran like 45 in my terra grapplers and if I recall correctly the same in my MTRs back in the day

 

You know, I remember one certain instance on the interstate the other day, it almost felt like bouncing or hopping and almost felt like for a second that I didn't have control... As long as it isn't a big issue, I won't worry. I mean I expect for ***** joints and stuff like that to wear premature now, and I realize I am putting more stress on the parts, and a tie rod or something else is now more prone to break. But its not like I am gonna go 100 mph down a dirt road or something. I guess I am just looking for peace of mind that its rougher, but not exactly harming anything...

 

Running more that 40 psi is way too much air. Recommended pressure on the stock tires is 35 psi, so with a tire with a higher weight capacity is NOT going to need more air than that. Bleed them down and check out the ride.

 

i originally had 50 psi in my 35's caused them to wear to much in the middle, dropped it to 40, helped a good bit and started wearing much more evenly

 

Alright guys...I am gonna try that...Thanks a lot

 

My first truck, don't know much about vehicles.

Back then I put on some new 33's Toyo A/T, few days latter I went on a long(2 days) trip.
On the road I once reach an uneven road area and felt like I lost control for an instant.
So I lowered the speed down from then on.
Latter, when I arrived I took the truck to a carwash, I was chatting with the owner about truck stuff, I mentioned the lossing control issue, he told me to check the tire pressure, and I was surprised I didn't ever think of that.
So I went to a Gas station and checked them out...

3 tires were 50psi and one was almost on 70psi.

Practically I was riding on 4 basketballs I guess.

I droped down the PSI to 38 and I felt less stiffness,

Still I don't know your case specifically but that's my experience.

I now have 35'' MT Toyos, I haven't have a problem. I do notice a difference between my brother's F150, my Mom's F150 with no Leveling Kit and mine, their trucks run smoother.

 

I think that the heavier tire is making it more obvious that your shocks are worn out.

 

62,000 miles and worn out?

 

We are talking shock absorbers and tire pressure right? It used to be 25K miles was the replacement interval for shocks...

Do you know how to check your shocks?

 

Dang, 25K on shocks? Never heard of that, not doubting you, just hadn't heard that. Do you get more life going with a Rancho or ProComp shock? Thanks.
