Just so you know what those 22s and rubberband tires are doing for you....

I too am enjoying the education. Thanks everyone.

The stock rims were quoted on here to have a weight of around 30lbs. With tire on there Id have to guess around 50lbs a wheel. So there ya go Rodrunner. To 2010_5thgen, so you are saying your rims will be around 10lbs, and the tires are around the same. Id really like to know myself what this less than 25lbs rim and tire combo is. Like Junkie said unless you are paying for a competition rim, but most I have found dont go above a 20" rim, I dont see it happening.

When he laid into the throttle, he went sideways across three lanes and back before getting the car back in shape running the Evo down at 120. That was on 18s and a hell of a sticker compound than you can get for a 22. Awesome to watch, but imagine what that car would've done on a 22" street tire.

Is that a true story?

Yes. The -V is actually really well known around the NJ/NY street racing scene. Has an LS2 403 stroker with a big cam.

Wanna see a GTO do it too?



How about a Vette?




I have too much self respect to make up some bullshit story to impress people I'm never going to meet on the internet.

Was that from a dead stop? Or a roll start? My friend had a mustang blown to 500whp with 4.10 and that never happened to him. He just had to be careful when starting from a dead stop. I hear what your saying. My tires are gonna be 315's to help with grip. we will see.

Class is in session -

The 3860lbs is the curb weight - The car sitting, looking good, on the street in front of the mistresses house. No poeple, no luggage (okay maybe an over night bag in the trunk). Yes the car does weigh that much!

http://consumerguideauto.howstuffwor...-camaro-13.htm

The 6942lbs in the gross vehicle weight rating - The kids, the wife, and all the lugagge you can pack. Driving to the grand Canyon for a two week vacation.

I had a guy driving from Boulder CO. and going up to Victoria BC Canada coming through LA in a 911 Porsche. He bought his wheels and tires put them on in LA and had his stockers shipped back to his house in Boulder. They drove all the way up to Canada and back to his pad in Boulder, fully loaded with all his girlfriends crap and an extra luggage rack. You may not do that but some people will. I have to make sure your wheels will exceed the GVWR for that reason. Make sure you wheels do too. FYI

if i ran 22's i'd run a 265/30zr22 in the front and TRY to fit a 305/40zr22 in the rear

That was a 3rd gear punch from a 60mph roll. Watch the videos I posted. They'll show you exactly what happened, except he stayed in it.

A 305/40/22 is a truck tire. That's a VERY tall tire.

Very impressive...But that was ~680hp @ closer to 40mph

How about a Vette?



No

That's too bad, gonna be some good ol boys from here, at Carlisle next week.

I think this is great info from COR and Mojo... but I think what most people arent realizing is making a huge difference in performance is the profile height of the tire. Not just the weight of the wheel/tire combo. Those rubberband tires are hard and not very sticky at all... they arent going to flex and grab the road very wheel in hard cornering and definitely not during hard acceleration.

And also on the street, you're gonna feel a difference in ride quality. Most people dont realize how much your tires help absorb the impact of uneven pavement and potholes. With the little rubberband tires, there's almost no give. So another part of the car has to give.... the shocks get worked harder, the frame gets worked harder, and so does your body.

I think the 20's will look fine in an aftermarket wheel setup that pushes the wheels out a bit further to fill up the wheel wells. The above is really the reason I want to stay with 20s, I want to have a decent amount of sidewall. Plus the tires are MUCH cheaper!

[Doc]

If you're thinking of running 550whp you need to talk to some performance experts. I'd be seriously concerned about safety running that kind of power to 22's with rubber bands. Take a look at drag racing cars; notice the small diameter rims with tall sidewalls? You need the tire to flex to help absorb some of the torque. Unload a ton of h.p. into 22's with no sidewall you may just spin the rim in the tire. Ask a pro speed shop you respect before doing this; they'll educate you as to what would be best to do and why.

[Doc]

The stock rims weigh 32 lbs. The lightest street rims I know of are Enkei RPF-1 which in a 19 x 8.5 size weigh 19.8 lbs. The weight goes up with rim size. 22's are not going to be lighter than a 20, and 22 size tires, even Falkens, will be heavier than a 20. If you've found a tire and rim combo in a 22 that's lighter than a 20 combo, I'd sure like to know what they are. I literally ordered a 1SS because it's lighter than a 2SS so I'm VERY interested in saving weight.

275/40/20.

The way it works is the second number, the sidewall number, is entirely dependent on the first number. The larger the width, the taller the sidewall. A 305/40/22 is going to have a higher sidewall than a 275/40/22.

The 305/40/22 is 3" taller than the stock 275/40/20.

A 305/30/22 is only half an inch taller than stock, which is almost acceptable. However, it has an inch less sidewall because of the larger wheel, which means those tires will be very hard.

The general rule of thumb I have always heard was that adding 1 lb of rotating mass was the same as 6 lbs of dead weight. If you put on a tire wheel combo that is just 10lbs heavier then stock, then that's the same as adding 4x10x6=240lbs of crap in your trunk.
