tires out of round because of bent wheels

[doris_young]

I had new tires put on my motorhome about 4 months ago, noticed a bad bouncing on front tires, took it back to dealer, was told I had 5 bent wheels on the unit, and now must buy new wheels and tires, as the tires are out of round because of the bent wheels. Could this be true, and why was I not told of the bent wheels when they put the new tires on.

Doris!
Please come back and tell us the results!

For your tires to bounce do to being out of round you should see 1/4 in or more.

Don't know where you got the idea that 1/4" or more is the lower limit, but your high by a factor of 3X or so. A tire that's out of round by 1/16" or less will be quite noticeable. I just had a shop true (lathe) six Goodyear tires on my MH. One was radically out of round, in excess of 1/8". The others were out by much less. Removing defects much smaller than your 1/4" will make a radical difference in how the thing rides and rattles.

I "got this idea" by measuring how much the my tire was of round. The OP describes "front wheels bouncing baldly" a tire that is within a 1/16 won't do this. When my mine were under 1/8 in the bouncing ceased but was still very noticeable. I have not been able to find anyone in Ct. that still trues tires but that is the best way to get rid of out of round tires. Even brand new tires can be slightly out of round.

Sorry, but I still strongly disagree. If you have a tire that's 1/4" out of round, you are at the outer extreme of totally defective. Truing a tire of this caliber would mean leaving areas of deep tread and others with little remaining, or even wear bars showing. But, you're relying on the OP's definition of "bouncing", whatever that means to him, and he is no longer contributing to the thread.

On my 2006 F53 chassis, an out of round front tire, well below 1/4" out, not only created a horrendous ride, and extreme vibration through the entire coach, but it also created oscillation and vibration in the steering column, and seat which certainly could be described as bouncing. The experience was similar to driving down a set of railroad tracks and bouncing off of every tie, once the thing hit 40+mph.

I am just relaying my experience. When I returned from a trip to Alaska my front end were worn and springs were shot (I had very little ride height) the tires were severely scalloped and out of round. When they were put on the rear my son following me could actually see them bouncing up and down leaving the ground. Front end was fixed along with HD springs. Adjusting to a lower tire pressure helped as well as several thousand miles of wear tires stopped bouncing(tires coming off the ground) but the front seat would still shake and cushions on the couch would vibrate out of place. Only new tires fixed this.

What chassis and year is it ? Our 1999 F53 chassis had 6 of the 8 wheels out of spec. The Ford dealer replaced them as a warranty issue. I was told it was pretty common that year. At the dealership they had a huge pile of bad wheels stacked up out back.

Actually, this thread is one of many that was moved from forum technical support. Maybe if the (fts) were moved to its own category, there would be less confusion, or just eliminate it since forum help and support goes to the same place.

We seem to have lost op.

In this case the RV can be driven after all you drove it to the dealer.

I would drive it to a Tire Dealer and DO NOT let the dealer know which one or suggest one.. And get a 2nd opinion

This I know: IF the rims are bent, there are places which specialize in fixing that... Usually cheaper than a new rim and in most cases they do good work,, Never had a truck size rim done but have auto size a few times. Unless you are in S.E. Michigan you will have to find the shop yourself.

You also (usually) have to remove the tire yourself or have a professional tire service do it Good tire stores will know the rim-fix shops in your area.

ALSO Tires that are slightly out of round can sometimes be "Trued" yes, this adds wear to the tire, but in the long run a little wear in the RIGHT spot means the tire lasts longer.

Again, You will have to find the true-shop.. On this one I can not even help you in S.E. Mi as I have never dealt with such a business.

What type of RV are we talking about. Early Fords had some rims that weren't centered on the hub and had to have spacers on the studs. If yours is one of these it could be tire dealer lost spacers and now your wheels are not centered.

[myredracer]

It seems to me that if rims were bent, it would be sideways. Not sure how a left/right bent rim would make a tire out of round? A rim would have to be seriously bent sideways to cause it to be out of round.

More businesses need to be legally accountable for deceptive practices like that. It would be interesting to try and get that in writing, then stand there with a witness and camcorder as they pull the rims off and demonstrate how bent ALL 5 rims are. Would make a good TV news story.

Do they own Joe's Used Car & RV Sales right next door too?

WOW, no way do you have 5 bent rims unless you drove your rig down a set or RR tracks for 100 miles going 70MPH. I can possibly understand maybe one bent rim or 2 if they are both on the same axle. You would of had to have hit something with your rig in order to bend them so you would have known.

Get that second opinion.

[hooligan]

When I replaced the 1st set of tires on this motorhome, as the mech put each wheel on the spin balancer, they all showed a wobble, 'bent rims'. The owner said "not possible"... He checked and found they had used the wrong centering cone for my rims.

Agree you need second opinion... Also, to me a bent rim would cause a side to side wobble/shimmy.
