I've been using this combo for about 3 weeks now, and I would have to say my car handles like crap...before when I just had stock 18's and Eibach, handling was perfect, very responsive, minimum oversteer. As soon as i replaced it with 19's and Toyos T1-R, I noticed my car freaking wobbles when I turn back and forth. I don't feel safe at all going above 80's, and my car has a right pull, even after an alignment.

Does anyone else have this problem with their T1-R? or is it just me? Do I need sway bars? It just doesnt make sense that my stock tires handle alot better. Any ideas? Thanks
btw the tires are 245/35/19 F and 275/35/19 R

 

Are you sure the difference isn't from 18s to 19s?

 

To be honest, I don't know if that's it or not. I wouldnt think going to 19's would actually decrease handling, esp with lower profile tires

 

yes they certainly would if you increased the weight of your rims and tires. Are they crap 19"s (ie not forged) bc if they are odds are they are heavy and you just added about 10lbs of unsprung weight to each rim which is a whole lot. Also the difference in tires could be to blame but the pull to the right im not sure about.

 

Thanks for your respone guys, actually they are volks gt-v, so I dont think they are super heavy or anything. I'm really thinking it's the tires, I've read they have a soft sidewall...if anyone else have these tires, please share your thoughts. thanks.

 

I think its just you to be honest. I have the Toyo T1R and love em. Your car wobbles??? Somethin doesnt sound right

 

Visionboy,

Did you install hubcentric (its a ring) ?

Tony

 

first off, hub centric rings sound like the problem.

other problems could be this.

1. I hate toyo's, i've had such bad problems with them and i hate their sidewalls. They are so soft.

If you were to cruise on a straight flat surface at like 40 mph, try jerking the steering wheel back and forth slightly. If you feel floaghty and the response is draggy, its the side walls on the tire.

2. added weight for the wheels does not really effect steering. Its added weight, don't get me wrong but its at the wheels that are in contact with the ground.

Just like in golf, a new bigger grip will make the overall weight of the club heavier but because its added weight in your hands.

I think its either the hubcentric problem or the tires.


hope this helps

Hi, thanks for the response.
Yes I have the hubcentric ring, I'm pretty sure they are put in properly, but I can double check.

Yes, as you described, when i jerk the wheels back and forth, it's very floaty, kinda like driving a boat...I did not expect this from Toyos. I was hoping it's something else but everything points to the tires. Also I got the wheels from online vendor which came with the wheels mounted and balance already. Maybe the wheels are off balanced?

I don't think I'll be going with Toyos again, I'll be looking for better tires...

 

I felt the same wobbliness when I put on my 19x9.5 +22 and 19x10.5 +22 and toyo T-1s. I have since changed to hotchkis springs and set the hotchkis sways to stiff/stiff, and that worked for me. I don't think it's entirely the tires, and would suspect that it's due to the more aggressive wheel offset that changed the shock's effective dampening ratio.

I don't have the wobbliness anymore, but I remember being thoroughly disappointed with the suspension system after I "upgraded" the wheels.

 

I have the toyos as well, and before them i had the dunlop sp9000's. I liked the Dunlops about 10x better, i dont think there is any comparison.... My next set of tires will 100% not be toyos

 

I just installed Toyo T1 Rs and they perform just fine. I did stick with OEM tire sizes.

 

I had a chance to go back to my oem wheels for a recent track day, and was astonished to find how much poorer the RE040 in stock size was compared to the 245 and 275 T1-S combo. Granted the toyo's were larger and the wheel offsets provide wider track, but my lap times suffered miserably. I lost 6 to 7 seconds off my average lap times on a 3 mile course. I really like these toyo's, and would definitely get another set...looking forward to trying out the T1-R's.

I have some new continental tires that I'll be trying out next, and I hope they will be at least as good as the toyos. Where do you guys get your T1-R's? And how much are they delivered/intalled?

 

I have the same wheel width and my car handles sooo much better over my track 18's. Visionboy, with Toyo's it seems like a love them or hate them. You are like the 6th person I have seen post up about feeling loose/wobbly steering after running these tires. What psi are you running them at? Try to go with a different tire next time. I recently went with BFG KDW2's aside from looking great, they handle great as well.

 

Not sure about the T1Rs, but I can give a bit of insight on the T1S and RA1s. The T1S' are by far the lightest, but don't have as rigid of a sidewall as say the S03s. Don't forget that the T1S is also a 5+ year old design and that is also several pound lighter than the S03. Having used the S03 for track duty about two years ago, I will attest it's a good (albeit heavy) tire, but the T1S is pretty damn good on its own. I run 245/275 on my street wheels, and I have zero issues with it around town. For the track I run 275 RA1s all around, and while the it's a different tire structure, I think much of what you read about the T1S' from online reports is BS. Sure the sidewall structure has less integrity than some of its competitors, but it's not that bad... since you save several pounds a corner, it negates many of the effects of having a softer sidewall. Again, this is on the T1S, not the T1R. For anybody making a blanket statement on Toyos, I can tell you that a SIGNIFICANT portion of track junkies run RA1s since they are predictable and linear, and have a very useable lifespan.

 

....the key may lie in the fact that you mention your car wanders even after an alignment?

What were your before/after specs? What type of machine? When was it last calibrated. I found this out the hard way after bringing my car in 3 times for an alignment at a local place that had a nice relatively new, Hunter machine. I would get it back, car would drift, feel just "wrong", and steering wheel was centered, despite having acceptable readings on the printout. Finally brought it to a friends shop in CT (drove 1.5 hours to get there), and we did baseline measurements - turns out shop #1's specs were not even close to what the car actually was running - their machine was woefully out of calibration.

 

Guys , thanks for all your help.
I've tried playing with the tire pressures but no difference. I keep them at 38psi.
As far as alignment, I'm not sure of it's accuracy, but the handling was pretty much the same before I had it aligned.

I'm going to try different brand tires next time hopefully it'll be much better.

 

I have the toyo T1R's on 19x8.5 and 19x9.5 on Axis Hiros. I felt a VERY small loss in accleration, but I took it up to 145mph on this setup and it felt kind of unstable and backed off What tire pressure should I be running?
