Hey i have sceen a couple classics stangs with the bigger tires in the back and smaller in the front. I was wonderin what advantage is there to doin this? And also is there anything you guys reccomend i do to my 68 302 coupe.

The bigger tires in the rear give you better grip in racing situations. You have to have some serious mods to the engine, tranny and rear end to justify those. For a daily driver, you don't want or need that.

 

well, a friend of mine did that but seriously toned down. he put 15's with slightly smaller sized tires on in the front. gives the same effect, kinda. i don't remember exact size.

 

two diff. reasons. some for performance and some for looks. people just like the aggresive stance it gives from the rear when you have the wide tires. and some like to have more grip while on the tracks. i love that wide rear stance and its what im gonna do with mine when the time comes

 

i'm thinking the same thing. i'm gonna go with the same size rims, smaller tires in the front and taller and wider in the back.

 

yeah i think it makes for a pretty awsome look i dont think i will have the money any time soon to do it thow.

 

The only advantage gained with a signicant tire width difference front to back is a decrease in rolling resistant and weight, meaning the only gain is for drag times.
Significant tire width decrease in the front versus the rear will make the car unbalanced and decrease street turning performance.

I tend to fall on the other side of the fence than most people and attempt to keep my car balanced with 255 40 17 in the rear and 245 40 17 in the front when I am on the street. I do up the rear tires to a 275 40 17 when I am drag racing, but it is for the better compound of the drag radials which I got DIRT cheap. When they wear out I will most likely run either a 245 40 17 drag radial or be stepping up to a slick.

 

It will make your speedometer off.

 

I've spent the last couple weeks researching and figuring things out about this topic. Here's my conclusions:

If you're running STOCK front end - arms, springs, strut rods, etc.... you want the front tires to be as close to stock running weight as possible, since this is what the suspension was designed for... I believe this is called unsprung weight. I had big 225/55 16 tires all the way round, and it just didn't "feel" right. Stuck real good, but something wasn't just right...

Here's what I've got ordered:

TQ Type 185 "Rod Wheels". 5.5 inch wide in front and 7 inch in back.
BF Goodrich Radial T/A 195/60-15 in front and 225-60-15 in the back.

This will add about 3/4 inch of "rake" to the stance, should provide plenty of hookup for the 289 and trac-loc rear, and keep the front on the pavement when cornering. Plus, the weight up front is darn near stock. (Don't know tire weights, so can't be precise just yet...)

These rims are really cool - google them and see what you think... Not too many sharp corners for dirt to collect, and chrome for lots of sparkle.

Best thing is, you can get them at Sears!![IMG][/IMG]http://www.highland-tech.com/67oldy.jpg

 

I like the look. I have been racing my 67 for the last 13 years with 28- 10.5 slicks. I am now putting back on the street with a stock 5.0 FI with an AODE, 2.45 gear ratio and I am runnning a 27X9.5 tire on the rear. It looks great.
