315's on a deep dish in the back or 285's on 17x9 in the back. gona run 245's on front.

now the thing is i dont wana be weighed down, so if the 315 on a DD dont make much of a diff id do those, but, i have a GT, not a Cobra so it seems 315's might jsut be a waste and ill get enough traction with 285's.

i thoguhtt my mind was made up wiht 285's but i jsut wana see what u guys have to say about 315 on a deepdish weight wise.

nitto 555dr's on the rear of course

while the DD look nice its alot of extra weight that will slow you down. hence why i stayed with the stock 17x8 wheels.

100 lbs is about .1 loss in the 1/4. not that much of a difference,and its only about 20 lbs difference. go with 315.

spike_africa · 01-07-2007, 07:19 AM

100lbs of dead weight aka not rotating mass is ruffly .1 in the 1/4. Every 10lbs you add to rotating mass ie,wheels,tires,bigger rotors,flywheels etc.. slows you down .1 in the 1/4.

So 100lbs of dead weight added or taken out slows you down tenth in the 1/4 mile.
an 10lbs of rotating mass added or taken away is worth a tenth int he 1/4 mile.

I'd go with 315 on Nitto's because Nitto's run much smaller than other tire brands.

Also, I hope you have stock 17x8 size wheel up front to run 245's up front.

yes sir i do

Go with the 315's it will look 10 million times better and there really isnt that much weight added.

315's are alot more pricey than the 285's unless you're doing a drag radial...

r3dn3ck · 01-13-2007, 07:51 AM

there's no reason to have that much tire... grip doesn't come from bigger meats, it comes from a good suspension setup. Bigger wheels... nah. Stick with 17x8 w/ 245 to 255 tires or 17x9 and no larger than a 285. There's is a significant weight difference and you'll save the constant rubbing and extra cost. If you can put the same size on each corner then you could even do a front to back rotation which can add many miles to your tire life.

I think redneck si 100% correct. Often times, what he said gets over-looked. In fact, many guys setup their cars and often times slow them down w/o realizing it.

However, you have to balance "looks" with performance and it becomes a personal decision.

I have 315's....I had them when I was n/a. Now that I am blown, I probably need them more, but they still slow the car a bit. But, I love the way they look.

yea thats why i was asking. 315 doesnt seem necessary for a GT's power when its not blown, but if the weight wasnt significantly different i was thinking about putting them on, but i think 285 is gona be good enough for me.
