Updated 09/28

In the last few months I have gotten tuned with Osiris and added a MD VQ exhaust and I'm having traction issues. I drive an 05 sedan with a 5AT, intake, plenum spacer, and I'm slightly out of spec on camber in the rear.

The tires are relatively new with 7/32's left and when I get on it I'm breaking free all the time at speeds up to 40. I went to pass a truck/trailer on the service road to the freeway today, stomped on it at 40 in drive and the back end let loose, smoked the tires a little, and fishtailed until I let up. VDC was off of course. Needless to say my first reaction was a big smile, but I need more traction than that since I plan to track my car soon. Also it's been hot as hell here so the tires should be extra sticky because the roads are scalding hot.

I was looking at replacing the Hankooks with Yoko S Drives, had them on a previous car and they were grippy as hell, but they don't offer a 225/40/19 which I need to keep my fitment on point up front. So does anyone have suggestions on a grippy UHP summer tire that's relatively quiet for under $250? With my camber and the fact I drive between 18-20K miles a year spending $400 each on tires isn't an option.

Thanks for reading this long post and let me know your thoughts.


UPDATE

I think I have figured out the issue. I just got back from a 3900 mile road trip out to Cali and back and drove in a variety of weather conditions. I didn't have as much of an issue with slippage in the cooler climates, but could replicate it in Phoenix when it was 108. I now think my issue is temperature related as we've had a brutal summer in Austin. Fell in love with the tires again on the road trip. They performed like they did when I bought them and that made me smile.

 

Vtec bro its tight!

 

You broke traction @ 40,beast.
Sorry I have nothing to bring to the thread

 

SS I should've known that was coming at some point.

 

What you putting down? I have all seasons and in the dry they can keep the grip in a straight line, the V12 are nice tires so I wonder whats going on?

Have you tried doing something like that again? Might just been a bad part of the road.

Also IIRC you do not want normal street tires to get too hot they actually loose grip.

 

I don't get it either.

 

That's strange I love my v12's and they seem grippy as hell to me. Try Sumitomo HTR-Z, Falken 452's, Michelin Pilot Sport, Hankook RS3, Nitto Invo. All decent tires but they all seem to be just as sticky if not less sticky than V12's.

 

Yes it does it all the time. I forgot to add I have done the 3.5 VLSD diff swap, but it started when I got tuned. It got more pronounced when I added the exhaust. I'm a little skeered to add the ARTS in a couple of weeks. (totally kidding I can't wait!)

I didn't know about the heat/traction thing, thanks for the info. That might have something to do with it as well as my rear camber, but RC is at -1.8 which leaves most of the tread planted.



Edit: I'm only putting down 250/232 but that was before the exhaust. I have an appointment with Uprev next week for a re-flash to see what the exhaust added.

 

I've run the Falkens (hated them) and Nitto 555s but the 555 traction was worse out of the box than the V12s. The Invos don't seem to rate any better than the 555s as far as traction from what I've seen. I guess I'll start looking at Michelin and hit up Tire rack and pore through the reviews of other tires. It just sucks Yokohama doesn't offer the S Drives in the size I need. I really liked those tires.

Also, I'm limiting myself in my search because I want tires with symmetrical tread so I can pull them and swap them side to side every 8K miles to combat my slight camber wear.

Thanks for the suggestions.

 

HTR Z are swapable from side to side I had mine swapped due to camber wear but thr not very sticky & thr noisy, idk if the pilot sports are swapable

 

What is your camber? If it's too much, you're not putting all of the tire's width on the ground.

 

Yokohama AVID ENVigor?

 

Read much?


J/K I know that has a little to do with it, but my camber's been where it is for a year and this didn't happen before the tune and exhaust. I can take off in MM and if I shift right I can bark 2nd every time. And no I don't have the Transgo, that's a stock 5AT with 92K miles on it.

 

Even though those are all-seasons they intrigue me. Have you ever run them? They fit all of my criteria except for being a summer tire and I'm not hung up on that.

 

I run them now and love em
