New Toyos Vibrating

[Magnet 2112]

This is a repost. I'm trying all forums for a quick answer. Just bought a set of Toyo Proxes T1rs 19" and had them put on my 2006 g35. I am very happy with the ride and lack of rumble the Bridgestones had. The only problem is that at speeds around 70 and above, I get an undulating vibration. The front and rear were aligned and the tires were computer balanced. Do you think it's tire balance or alignment or would the fact that the car came originaly with the 17 inch tires and I put the 19" Infiniti wheels and tires on it make a difference. Going back to Town Faire Tire in the am. Any help would be great.

sounds like thay need a rebalance to me

[vijaysingh]

Try havin' them do a "road force" balance. You might have a bad tire

[gwoods]

Either out of balance OR radial run out

Tell the person balancing the tire what speed the vibration is occuring at and they can do a better job with the balancing.

Check the date codes on the tires. Just because you just purchased them doesn't mean the tires are new. They could be years old with a problem?

Could have a separated belt. Back to the dealer who sold them to you.

Date codes need to be checked prior to having tires mounted on a vehicle.



This tire was manufactured in week 01 in 2008

Update: I brought the car back to TFT and they said first of all that I can't drive over 50 for the first 24 hrs because the weights are glued on! Then they also said that one of the back tires had a bounce to it. So they ordered another one. After 2 days of driving 50 on the highway and almost dying, I still have a slight vibration around 75mph. As for the tires, the ride is smooth and quiet but lack the lateral grip of the potenzas. It depends on what your looking for. I will take the better ride and watch the corners

I've NEVER been told that!! On the next set of tires, I would find another store.I had some Toyo's on my Pathy that gave a vibration at HW speeds.They had to remount & rebalance the tires. Turning the tire on the wheel and rebalancing did the trick.

[Magnet 2112]

I will say this, I am suprised that the lateral grip of these tires don't even come close to the Potenza's. Every corner that I used to boot around and not even think about slipping I now have to be very careful. TFT has a 500 mile test drive, I may see if I can trade them in for Pilot Sports.

[SVTCOBRA]

I have RE750's on my cobra and they've been great so far. My second set. I will be looking at Potenza's again, if I ever wear these out. I put less than 2K on the cobra per year.The Toyo's I had on my Pathy were crap. I replaced them with Michelin MTX?. But, I've been told that Toyo makes much better tires for cars than trucks.

[Magnet 2112]

I would agree so far about the toyos. The Potenzas were way too hard riding and deafening but obviously if you want a good ride your going to slip. I did alot of research before the buy and it seemed these were going to be great but so far not so much

[SVTCOBRA]

I don't hear anything other than the motor when I drive the cobra!! actually, the 750's never made any noise even when they were low on tread. But, all model tires are different.

I still think it sounds like a bad tire. I have never been told that you can only drive 50 mph after they mount them!

I always do many 0-120+ trips with a new set of tires just to ensure that they are right and balanced!

The tires are starting to grip a little better. I told TFT that I wanted to get different tires. I looked into Pilot Sports and they said they would exchange them only problem is that they are on national backorder. $390.00 for the upgrade. Still haven't got the slight shimmy out of the toyo's. I can feel it slightly in the wheel but mostly in the seat. TFT claims that if I let the tires break in they will be as good as the potenzas. Going in for another re-balance. 5th time of driving under 50 for 24 hrs. Driving to work in Boston is like Russian roulette at this speed.

Reading your post sort of $isses me off but that is exactly the reason I returned to the dealer for OEM tires

The tires are great, my vehicle handles great and the dealer replaced two tires manufactured in 2003 at no charge. I've had my G up to 110 for a very brief period with no vibration.I think your tire dealer either stuck it to you or doesn't know what they are doing

I concur. Have the roadforce balanced. You can go to Hunter's website (Manufacturer of the Road Force balancing machine) and they can tell you which chops in your area have the Road Force machine. It will cost a bit more, but this balancing machine can reveal a lot more about your wheels and tires. It can also remedy slight variances in roundness of each by matching the tire's high spot with the wheel's low spot.

The 50 mph for 24 is a load of

I'm not going to get into the physics, but it doesn't take much "stick" to keep a 1/4 oz weight stuck to wheel. Especially since the weight is getting mashed into the wheel every time the car moves.

[Magnet 2112]

I guess the question now is do I get the road force balance or go with PS2's? The reviews are very good and I'm only $400 away at this point. Is anyone running the Toyo TR1's? Have you heard of any balance problems?

[Sentientbydesign]

Isn't Jacko running those?

[Magnet 2112]

The tires seem to be settling down now. Grip has gotten much better. I have searched far and wide for a shop in Mass that does road force balancing with no luck. I am going to my regular shop because they told me they could balance them and I would be able to drive over 50
