Heat in the Mickey Thompsons

[guscorty]

Hi Everyone,

I'm running the Mickey Thompson Street Et Radials on my car. Someone said to me that I wasn't putting enough heat into them in the burnout. Someone else said that they don't need much heat. Any advice would be appreciated.
Cheers

Big first burnout, at least 5-sec big smoke, then little after that. High speed burnout, rev it out.

They get worse when too hot
Slicks like more heat
Buy a cheap temp gun and get someone to monitor while you are staging

Small burn to clean them is all you need

what temp would you be aiming for?

The one that grips the best ;)
Try hotter, try colder...

Thanks for the replies everyone. Just changing the subject, at the last meeting I couldn't believe the difference changing the tyre pressure made. I went from 24 psi on the first run and getting bad wheel wheel spin, to 20 psi on the second run about 3 hours later and they stuck like glue. Admittedly the air temp was also slightly cooler and whether the track temp was also slightly cooler I don't know. A lot to learn.
Thanks Guys.
Cheers

we usually run 17psi, 3200lbs, 275, 15x10

They definitely hook, we found no difference between them and a slick in performance. weight is different about 6kg

I found 17psi cold which is around 18psi after burnout is the go on a decent track, running 275 MT Pro radials, 3900lbs, 1.3s 60ft 15x9.25 rims but I'm looking at getting a set of 15x10s as Paulie said! Burn out short and with decent wheel speed. You don't need to see big smoke, some of my mates call my burn outs soft, I just reply but I wana go fast!

I get best results around 20psi warm, 3960lb car, 275/60/15, 1.4s 60'

For 400 - 450rwkw in a Zf Miami sedan would I unstick 265/40/18 ET 2s?

I want to buy my first set of drag radials and mount them on 18x9.5 +38s

Would I be better squeezing a 305/35/18 on the rim, or does the bulge it would get on a 9.5 inch rim make the 265 a better choice?

[prasac]

the more sidewall you can get the better. M&H make a decent radial as well for IRS cars, check out VPW. Pretty sure they do a 275/40/18 and 275/50/18, either will suffice.

[Shonky.]

I guess I was hoping to keep similar diameter as the front so I can drive it to the track, but a low profile sidewall is probably too much of a compromise?

[ronnyBB]

Do you have to run a 18" rim?
For best results, the shortest rim you can fit over your brakes with the tallest tyre you can fit in the guard
A taller tyre gives more rubber on the track also

Yeah, I've got 4 piston brembos on the back which other than a few notable (and expensive) exceptions need an 18

I'll probably just get the wheels, dummy fit a steet tyre and then measure what it will take from that.

So sounds like the message is height before width.

If I turn DSC off will it drive to the track ok with way taller tyres on the back?

*sorry for the massive thread jack everyone*

Both height and/or width help
Do whatever fits

Dont even know what DSC is lol
Im old school

[prasac]

She should be fine driving on the street to track. Sidewall is good to a certain point then start going width. Put it thithis way they are running 4.8@163mph to half track on a 235 radial

Thanks guys

Dsc = dynamic stability control

It thinks different tyre sizes are a fault cause of different speeds
