Default Questions for 315/35/17 Toyo TQ or Toyo TQ in general

Anyone used the TQ (drag radials) on a road course? Am looking into the 315/35/17 & am concerned about the speed rating &/or whether or not the side walls are too soft. I do realize there are better options, such as road course slicks. Hoping that somebody has tried the TQ even if not in this size. Please comment even if you just know of someone who has tried them on a road course.
Thank-you


Tried Mickey T drag radials on a road course once & they sucked. Pretty sure that the TQ will be the same.

In my experience the TQ handles about the same as the 555R.

Interesting. In reference to the limited speed rating of the TQ (115 MPH); how fast have you had them? We need 130-135 MPH. Will they hold up?

On the longest straights we can reach 135 & is only @ above the rated 115 MPH for maybe 15-25 seconds. So, based on your experience, we will give 'em a go. Thanks for your input.

No problem. Yeah they should be fine for short bursts like that.

I run the 275/40/17 Toyo TQ on my car. Our local road course has drag nights on the front stretch, and after each race you drive a lap on the road course to get back around to run again.

In my experience, driving with these tires on a road course is very nerve racking. Driving at slow speeds they feel very vague in the corners, but any time I try to get on it and carry even just a little bit of speed into a corner, it feels like the sidewalls just give and the whole back end of the car feels very unplanted and unpredictable. I would not even think of trying to run these tires at any kind of HPDE.

Was afraid of that. Are you sure it's the tire & not from the drag race suspension settings?

Since last posting in this thread, have found that the Nitto is a much lighter tire & has more of a road course type of driving friendly design. So, now am leaning toward the Nitto, but, the higher 100 wear rating has me a little concerned about traction.

General comment: We have several different size slicks on hand. Just like to experiment & goof around w/ parts/set ups from time to time.

For what it's worth -- for handling, the 555R II excels (same compound as the 555R however with stiffer sidewalls) and offers good straight line traction on the street/drag strip. It's a MUCH more effective dual purpose tire than the 555R is. The 555R is rated to handle the speeds you're running, however it's unstable under any modest amount of load in the turns.

The NT01 is also another great dual purpose tire.

Looks like the only size available in a 17" tire is a 275 (NT555RII) & the 275 version only has a W speed rating. Am not sure if it's still being made, 'cuz could not find it on the Nitto site. The NT01 does look promising (315/35/17).

Decided on the NT01. Will have 'em mounted later this week. Thanks for the comments.

Did you ever run the Nt01's on road course and if so how did they handle?
