Advice on front tire size

erwin3523 · 06-13-2013, 08:18 PM

Hey all, just bought a super street car and it has 25" x 4.5" front runners on it. Car weighs about 3000 pounds. The stance is a little high in front but before I adjust the front suspension I was wondering if I should go down a size or two on the tire. I would like to run this car in super gas as well at events that don't contest super street. So, should I leave the 25" front runners alone and adjust the suspension or go down a size or two?

Also I wanted to get new rear slicks, what brand would be best for this type of car?

Thanks for the advice in advance.

Well Brian

I would try what you have and I would try leaving the front suspension alone at first. I think Super street is on a .500 not a .400 tree Lowering the ride height might add to the front end travel , lower your center of gravity and could slow you reaction times.
In general smaller front tires should reduce your roll out and improve your reaction times but if the car will go red with what you have why change?
As far as rear tires go I have used firestones, Mickey Thompsons and Hoosiers the Hoosiers have been the best for consistent quality. But I haven't owned a door car (Super Street) for 25 years. I think you need to talk to some Super Gas and Super Street guys with a similar suspension,tire size and power level. One thing you might want to consider is a stiff sidewall tire if your car has adequate tire under it they may also help your reaction times.
I think you should also provide a little more information on your set up, for instance what type of front and rear suspension do you have, 4link, ladder bars? Cal tracks, slapper bars? In my experience for example slapper bars when they work right will raise the back of the car at launch and therefore require more front end travel than a 4 link or ladder bar car to transfer weight properly. With the 4 link or ladder bar you may be able to reduce front end travel which can help your reaction times providing the car is staying hooked up.
Lots of variables here including the weight balance, power (torque) and over gear ratio in low gear but I'm sure some of these guys can help you out.
Good luck
