Answer me a question.

[Cobraman]

These: 555r for the rear, 555 for the front.

Have those picked out. Working on convincing my dad. The only issue is that I have 315/30's right now, and the biggest 555r you can buy is a 305/35. Is there gonna be a difference? and there is an issue with the fronts as well: I have 255/35's right now, and they are streched a little more than I like. Juco said that 255/40's would be the best fit, but nitto only offers a 255/35.

You shouldnt have a issue. I had 10.5 Cobra rims on my 04 Cobra with 275 Mickey Thompsons. Yeah they where stretched by didnt look bad or perform bad. I think you can get away with 305's if the rims are 10.5

I hope your dad tells you no, for your own sake.

Why? His Dad IS going to buy tires for the Cobra. It just a matter of choice now. Jeremy wants DRs for the rear, his dad wants a nice radial with more tread life.

Why would that be? I'm paying more than half.

Jeremy, the way you look at a tire to determine size is this.

The first number, in your case, currently 315, is the width in millimeters. The 305 being only 10 millimeters narrower, come out to be a little more than 3/8" difference. Not enough to even be able to tell a difference when looking at it.

The second number, 30, is the sidewall height. Which, in your case, the height of the sidewall would be 30% of the width of the tire (the 315). So, if that made any sense, you would be looking at the sidewall being 30% of 315mm.

Then, obviously, the last number is just the wheel diameter.

So, the smaller the second number, or the 30 in the 315/30-18, the lower profile tire it will be.

I'm not sure if you already knew all of that or not, but hopefully that helped.

So I guess to sum all of that shit up that I just typed, yes, you should be fine going from a 315/30 to a 305/35. The 305/35 will be about an inch taller than the 315/30 that you have now. This will take a bit out of the gear, but probably not enough to notice. It will only be about 3/8" narrower, so I wouldn't be worried about the width at all.

cuz of tha fo fyv sixxxxes - they make monstah powah

I've got Nitto drag radials and they spin like a mofo, even from a 3rd gear roll. I haven't done a big smoky burnout with them yet to see how much that helps (I'm sure it will, I just don't drive like that very often lol).

[Cobraman]

So I should get a taller rear tire? Would it look better/ help with the gear? So a 305/ 45 ?

[Cobraman]

How would a 305/40/18 look on a 10.5 inch rim?

Why? Because his first post clearly states he is looking for better traction on the street. But yeah, let's get another kid into street racing. Fuck it, tell pops to drop the coin on some Mickey Thompson DOT slicks.
