More tyre questions..

[montyv8]

Hi all..
I picked up some tyres on the weekend in preparation for my first outing to the track in May (AFF meet). I have a few questions about them, and running them on the car.
The car in question is my XB coupe (383/4500 stall/4.11's). Runs 295 BFGs on the street.
The tyres I picked up are 275/60/15 D.O.T. approved (treaded, sort of..) Hoosiers. They were on a Group N (i think) HQ circuit car. Used for one round or so, then replaced. I got them free, and can't justify buying a set of new tyres for what will possibly be the only trip to the track this year...

From what I've been told, if warmed up these are reasonably sticky tyres, and should do ok on the strip. Any comments, opinions on this? anyone else use/used these tyres for this or any other purpose?

the other concern I have is that as far as I know, these are cross-ply tyres. From what I have read these shouldn't be run with radials on the front, due to wandering issues etc. Is this just for cars that run over certain times? or is it a case of 'no matter how fast your car goes, you shall not run with mixed tyres'?

The 275's did come with a matching pair of 225 hoosiers, but are heavily cambered due to how they were previously used. I'm worried that running these on the coupe would be a bit risky due to the wear on the tyres not matching the alignment thats currently set on the car.

one last question - for now, these tyres have tread wear indicators on them, are they ok to use on the track all the way to zero tread?

all coments/opinions/advice welcome

Suggest you put cross plies up front. On the freeway they wander like all getout. At the drags, under accelaration though, its not so bad. What times do you anticipate??

[montyv8]

no idea, I've never raced on the track before so my driving will more than likely hold the times back, but the car should be capable of very high 12's.


I'll probably run 15's now haha..

I have the same tyres in the shed Phil,
I found them good for cornering grip when new,but I could smoke them all the way through 3rd gear on the power in the old XA.
I was keeping them aside for powerskids,IMO you'll be dissapointed.

One other thing,even when I had these tyres front and rear,they would wobble down the road like a drunk chook until about the 3rd lap..
These are very different to a drag slick..
I may be able to lend you my slicks for a run or 2 depending on how things go..

these are the tyres in question:





are these the same as yours Tony? anyone else have any comments?

andra RULE BOOK says

"cars quicker than 12.50 (1/2 mile) and 8.00 (1/8 mile) using independant front suspension and cross-ply rear slicks are not permitted to use radial front tyres".

LIKE NUGGET SAYS YOU WILL PROBABLY FIND THEY'RE GOOD FOR TURNING OFF AT THE END OF THE TRACK!!!

I know it's hard to justify for 1 meeting but if nugget is offering the loan of his slicks I would take the offer up.

Just remember you spend a lot of your hard earned dollars on engine and driveline and if you were to damage it because you just can't get traction It would be a waste.

I've never seen a golfer T off with a cricket bat and all drag race cars have SLICKS!!!!

Exact same ones Phil,they are still in my mates shed,also have tried the goodyear bluestreaks,which have a wider contact patch for the width I think.
I have a contact and can get these used quite easily,but have found them not worthwhile with the tyres available to me,these guys run them due to class rules,if they didnt have to they wouldnt.

Do they feel like they have a hard skin on them but softer underneath?

By all means try them,but leave yourself a backup plan is my advice..

High 12s eh phil? Dont think you will have too much trouble knocking a second off that if you take up Tony's offer. You still runnin the same converter? Did the gear change help??

That would be 12.50 1/4 mile not 1/2 mile btw.

I thought it better to go with that than say "oh it'll run 11's for sure" and then go slow as
Yeah same converter. I only dropped the diff center off on thursday lol... should have it back mid this week
The problem with taking up Tony's very generous offer, is he'll be racing on them most of the weekend..

Pffft, Tony's is a Wheezer, the slicks will bog it down. You'd give it a much better home behind a Clevo
