I don't race my car at the track but maybe twice a year so I don't see a reason in buying skinnies. Howvere, my Fikse and BFG's up front are heavy as hell and I'm thinking I could save an honest 40lbs (unsprung weight is equivalent to about 140lbs inside car) if i used spare tires. How much would it knock of my e.t., a tenth? I was thinking about a light-weight battery, no swyabar and spares up front. If my car runs 12.5, I was hoping that would put me in the 12.3-12.35 range. The main thing I wanted to know is if the track officials will let me do this. And if so, will it steer okay? Will it be any worse than skinnies? I just never heard or seen anyone else doing this before. Yes, I know it will be ugly. So what.

 

Spares are rated at 55mph arent they.

 

The answer is Hell No!

I agree,
They are rated for ONLY 50 mph & "Hell No".

You're not going to pass Tech.

It's not worth getting you or someone else hurt over!

I wouldn't line up next to you!

 

50 mph rating doesnt matter, you'll never get the tires up to temp.

The skinnies most guys run aren't even speed rated and many go very fast.

They won't let you run 2 spares at the track though.

 

seems like this question gets asked about once a month.

not trying to be a jerk, but wouldn't common sense tell most people that's a rather poor idea safety wise??

 

ive got a vid from this past friday night of a chick in a foxbody mustang using spares for skinnies and pulling them....go figure....pulled the wheels and ran a 13.04 @102. i'm running 11's-12s at 114-116 and couldnt pull them if my life depended on it.

 

Alot of people are using the Pep Boy's VW Tire. I think they are 165/70 15. They cost about $50 each.
For wheels get the CL Convo Pro 7.5 x 4. About $120 each. So for aruond $300 you can have a safe skinny's set up.

Using the spare tire isn't a good idea.

 

Doesn't the spare rim itself weigh a decent amount?

You could just mount pep boys tires on the rim if you wanted to...I guess that would be safer...
