Tires...

[maXmood]

CRC guys, enlighten us please..

to track our cars, we need slick tires. are there certain specs we should be looking for in tires?? e.g. resistance, traction, response, size, etc...

P.S. couldn't find a better section to post this.

thanks

Any tire as I know as long as it’s in good condition .

i guess semi slick would be your best deal, dunlops?
Q will be helpful in this issue

You don't NEED different tires to track the car during CRC events.

If it's your first time driving on the track i would advise against using slicks or semi slicks tires for two reasons:
- Most semi slicks (and all slicks) need different suspension alignment to work properly (less camber and more caster is usually advised)
- Tires will increase the grip of the car so if you are going to spin you will end up spinning at a higher speed that you would on street tires, if it''s your first time on the track you should learn how the car handles first and get some experience at lower speeds before you go all out...

Get the Toyo R888. Period.

thanks italian...

let's keep CRC on the side.. went down the market, and started looking for good tires to replace my oem ones. since i'm thinking of tracking the car in the future, i'd rather buy something decent than just getting the oem specs.

what should i look for in a tire?

yea, why? and why would i get these over Nitto for example. or even Dunlup 9000?

i mean, ppl can suggest tires that read reviews about, or even experienced, but to decide on which tires to pick would require lots of considerations, including the streets/tracks/summer/winter/etc..

dude, my tires are almost gone.. they have to be replaced soon.. not gonna risk tracking it, cuz now i'm afraid of taking a hard corner on them!

[Kayman]

dude, go in for fun... no one side anything about you going into corner in high speeds!

take your time, cruise around, be familiar with the track and how your car handles... that's what i did... i was so slow around turns even a stock GTI had better timings then I did!

but when the straights came along, the only 2 cars I couldn't overtake were john's z06 and Q's GTR... everything else was in my rearview mirror :D

Max: From my experience, i liked the grip of the R888's over the Nitto 555R's, Michelin Cups and the Advans for track.

The R888 was on my 800whp Supra and the Advans before it. The Nitto 555r is a very good tire, had them on my Endless GTR33 and they were great for street use. I have Michelin Cups on my 500whp DC5 Integra. They all dont like wet conditions but are amazing on street and on track, they do put the power to the ground without much drama. Havent tried the Dunlop 9000's. But i just installed the Spec V optional tires from Dunlop ( also doesnt like wet ) and they are much better than the Bridgestone Potenza's. Im not sure if they make the same tire for sized under 20'.

It depends, if you want them strictly for track i suggest the R888, i got them for my GTR for track use. For street use go for something like the Michellin PS2's ( ive tried them they are very good in all conditions, M5 owners change the Conti's for these ).

[BLOODLINE]

For the CRC? you dont need new tires my friend .. your tires would do believe me, give it a try :D

dude, not tracking it on these tires.. they can't and won't handle it.

nowadays, i don't even do aspirited driving, cuz i'm not feeling safe enough.

Thanks Q, that's a piece of information i was seeking..!

not tracking the car.. i was mainly asking the following:

- why slicks?
- why semi slicks?
- what standards/specs are we looking for?

if you all go back to my first post, i didn't say anything about CRC events.. i asked for CRC guys cuz they know the rules of tracking cars, and they can lay down what we should look for in tires for the track.

sorry if you guys misunderstood my initial post.

track days are coming... and this thread is about tires..

[NOS4EVER]

Stay away from Nitto 555r they won’t grip have them on my bird (front)
Lots of under steer till they reely warm they grip but not much.

You need much better suspension that what our F bodies have to take a corner on a track.

Maxmood, the tarmac on the track is not the same as the roads :)

thanks NOS, ADM...

I did 1:23 with my high stall only thing was limiting my
Time is the tires and high stall .
For the stock f-body the brake system sucks.

[The Italian]

The R888s are a good semi slick that you can drive to and from the track. They run OK with stock suspension geometries but to get teh most out of them (or any tire on a track) you should think of running less camber (especially in the front) so that the tire is flatter in the corners.

One think to look for in a track tire is its thread-wear, for example a good summer tire could have a thread-wear rating of 150 and the R888s are closer to 80. That basically means the tire will last half as much but will be twice as sticky :)

Stay away from real slicks, they are not meant to be run on stock suspensions (you will see real slicks have different reference for sizes, like two numbers instead of 3 for width. Example 24/64-18 )

You were picking up what time you lost in the corners on the straights :D your car has gobs of gut wrenching torque Mashalla :)

Aren't you running Hawk brakes? I got the ceramic pads with EBC rotors at the front. Best mod I made to my car so far.

thanks for the info!

what determines a tire being slick, semi-slick or street?

are there certain specs that classify the tire?

For a tire to be road legal it has to be able to be driven in wet conditions, that means that the tire needs to have some grooves in it so that water can be expelled to prevent hydroplaneing (float over water at speed)

http://www.smartmotorist.com/images/driving_guideline/hydroplane.gif

A slick tire has no grooves or cuts on its surface, it's just flat rubber, it's not road legal

http://www.f1fanatic.co.uk/wp-content/uploads/2008/07/slick_fif1_barc_test_2008_470150.jpg

A semi slick will have a limited number of cuts or grooves, enough to be road legal but still allowing for a lot of grip. Driving with these tires in very wet conditions would be dangerous.

Road tires need to be able to handle very wet surfaces, that's why they have more grooves.

Italian, i don't know how to thank you.. :D

wish we had a rep system on this forum...

still looking to learn more in this category.

thanks a bunch!
