I have a 2000 Trans Am was just curious how big of a tire i could do without having to really grind the caliper or work on the wheel wells. I really like the MT ET Streets personally. Also i was wondering i will be Cam, UD Pulley, minor bolt on's (not intake manifold, TB, or heads). So prolly high 300 rwhp and full suspension including dana 60 rear end and was wondering if MT ET Streets would be tooo much tire for that low of hp and if it would hurt me more then help??? You're input will greatly be appreciated!!

 

no love for MT ET Streets out there??? sigh....

 

I have 295/45/17 on rear. needed to hammer inner fender well alittle and no fender roll required......

 

I have 325/50/15's and they fit fine after a little hammering. Not a big deal at all.

 

what size rim?17?

 

I haven't really decided with what Rim i'm going to use, i was pondering getting some Prostars while i'm at it cuz i think they look beast on that tire. So just gotta hammer the fender a little that's good to know!!

 

Just make sure to get the 7.5 bs

 

wait what is the 7.5 BS?? and my main question is will these tires be tooo much tire for my setup?? I wanted them because i figured they would be perfect down the road when i'm full bolt on's / heads / cam but right now when imma just be cam only and only rockin like high 300's is it too much tire??

 

Are you talking the MT Drag Radials or just plain ole MT ET Streets (which I wouldn't run on the street)???

Depends how much driving you do. If you daily drive your car I wouldn't put drag radials on it (unless you just like throwing away $$$).

I'm looking to buy some TTMs with street tires (275/315), and then have a set of Billet Specialties Drag Lites with drag radials on them.

That way I can switch back and forth. Anything has to be better then the little 245 KDWS I have now.

 

7.5 back spacing on the wheel. That is the stock BS'ing. If you DD your car don't use the Mickey's as they wear fast due to being more of a drag tire. I switch mine out at the track. If it is a DD car look at Nitto's. They wear much better. If you do go with M/T's you can get away with a 275 or a 295. 325 isn't needed.

 

I rocked 325/50/15s when my junk was exhaust/lid only. I now have a 28x13.5-15 tire, with a cam only setup. I have 15x10 prostars with 7.5 backspace. You DO need to grind with ANY 15 inch wheel you put on your car, unless you spend the big bucks for Bogarts.

 

15x10-----1. you need a 7.5 backspacing
2.alot of grinding of the caliper
3.there are more tire options with a 15x10

15x8----------1.you need a 5.5 backspacing
2.grinding still needed not nearly as much as a 15x10
3.if you ever decide to go with a bigger tire in the future you wont have as many options compared to a 15x10

 

Well I was looking at the regular MT ET Street tire, i was thinkin along the lines of near 300 so the 295 would probably do. I have a set of all season's on there now so those would be my DD tire and I would be using the MT ET Streets at the track / street races but that'd be about it. I have looked into the Nitto's but didn't think the 555R's would hold after i get some good power and want to launch it around 5k?? I could be mistaken though. I was just looking for a nice sticky tire i could throw on for track days where i wouldn't have to mess with caliper or anything that much!!

 

Alright man, not trying to be a dick, but it sounds like you don't know what you are getting yourself into.

First off, you need to decide what the goals for the car are going to be. After you figure that out, you need to decide on what kind of budget you have. Then after you have thought those over you can start saving a lot of money, because that is what it will take.

You need to think about what size of rim you want to run. If you are going to stick with factory 17's I would got with a 275/40R17 Drag Radial. If you get wider rear wheels then go with a 315/35R17 (at least a 10.5" rear rim).

If you want to go with 15's for the races and keep the 17's for DD the that is smart too. I would go with a 15x10 if I were you. It keeps your options open for lots of tire sizes. If you stay with the stock 3.42 gear then I would go with a 275/50R15, if you go up in the gear, say a 4.10, I would go with a 275/60R15 or a 325/50R15. But if you go with the latter, then you need to realize it is going to take more work to get them to fit. You will most likely need to roll your fenders and beat your inner fender to get those monsters to fit, it is by no means impossible, I did it on my car.

The next thing you need to think about is suspension. The fbody suspension has the right idea behind it, but the stamped steel stuff is not going to be any good once you start adding power to the car. If I were you, look at some good companies, BMR, Spohn, or UMI and start getting stuff from them. Suspension is something I would do FIRST!!!! Mainly because you are in no way throwing your money away by doing it. It will make your car faster now(ie. being able to put the power to the ground) and then in the future you already have your suspension done for when you do start moving up in the power grid. And as far as suspension parts go, I would get all adjustable components, if you ever do put a big tire on it, like a 325/50, then it will make it SOO much easier to fit them on the car.

You made a comment that kinda scared me in the last post, 5,000 RPM launches??? YOU CRAZY SON!!! Your rearend/suspension will not take that, on stock tires you will hopefully just spin the crap out of them. With stickie tires you might do the same, but when you start putting DR's on and lauch at 5,000 you better have about 3K saved up to replace the rear end because that 10 bolt WILL NOT take the abuse. I used to have 3 shelled rear ends in my back yard to prove it.

Your primary thing you need to worry about is your goal for the car. If you want it to be a bad *** street machine with tons of horsepower that can run 10's, you better have the pocket book to back it up, because speed is expensive. Once you start upgrading one part of your drivetrain, you will need to update more as time/power goes on.

But, at least you are in the right place, there are PLENTY of people on here that share your same passion and will help you when you need it. Read around on the boards in different sections before you start spending money, so that way you won't be throwing your money away.

Goodluck to you man!

 

Okay thanks for butchering everything i said dopdbrd. I just read your whole post and think with 1,302 posts that you would learn to read all of the posts prior to freaken yelling at someone. My initial posts tell you what i will be running, INCLUDING FULL SUSPENSION INCLUDING DANA 60 REAR END. Gosh dang all that useless writing you did when i said I will already have all suspension parts. I know exactly what will be done to my car and everything is already written out and calculated. So yes i will be able to launch at 5k rpm as i will have the Dana 60 rear end which will easily hold up to.

The first half of your post was lovely that's exactly what I wanted to hear but you shouldn't have put that second part. I am looking for a Good tire to put on my car for Track use, something that will hold strong on 5k launches with full suspension with as low as 400 rwhp and as high as 600 rwhp. I will still have my street tires for DD use so i didn't want to do much caliper work or tubbing or anything like that and i wanted to keep it so i could swap back and fourth between track tire and street tire (stock size rim). I have not thought of everything of course was just looking for some input on the situation so sorry for gettin angry!!

 

If your just going to use them at the track, get a set of stock firebird/camaro 16s and put some 26x11.5-15 M/T ET Streets on them. They will work good for what your doing, and you wont have to mess with any grinding, just bolt them on.

 

LOL I wasn't being a dick, just trying to give you info. Sorry if it came off that way but I wasn't yelling LOL.

I just want to make sure you have all the right components man, sorry for trying to help.

 

If you got the rear and an extra set of wheels why not go with the et streets instead of radials?

 

thank you camaro396 that is exactly what i was looking for. And TA1364 what are u talkin about? I said from the beginning that i wanted ET Streets instead of radials from the beginning?? Sorry dopdBrd i guess i just got a little nerd computer rage going, thanks for your input!!

 

Ok my bad I read the op wrong. I would definatly go with the stickier tire. I am in similar situation right now between the radials and et streets.
