No, I don't mean 235 individual tires... (you know someone would say it)

I'm getting new rear tires this summer, I'm not sure what size to get. I want to get 235 series tires, but do they hurt the handling due to the bulging sidewall?

Thanks for any info!

 

I never noticed a loss in handling when I went from my 215s to 235s. I didn't notice any more bite during acceleration either, but the Dunlap 235s had 1 more grove than the 215s, so I wound up with the same amount of rubber on the road. I did it purely for looks.

 

depends on the size of the rim, if you got a 15x7 wheel then it will bulge a little bit but wont hurt anything, if you got 16x8 then youll be fine, heck you can even run a 245 on a 15x7 wheel and be fine still, oh btw this thread should probably be in the suspension board and not apperance just a little fyi not being a dick or anything

 

WTF? What size wheels are you running?? Im running 255's out back on stock 16's without a problem and trust me, the bigger you go the better. 235's are actually a bit too small for our rims, unless you running 15's. I dont know what size they had stock. You can normally go one size larger and be ok though.

 

I have 15s,

quick question:

Will 235/60-15 tires be taller than stock? The front tires are 215/65-15.

 

Tire sizing
-235 is cross sectoin width,

-60 means the height of the tire is in a ratio of 60% the cross section is the sidewall height.
-R, means radial,
-15 is size of rim.

Stock 215/65R15 Tire radius-->13.00 inches dia-->26.00 inch
New 235/60R15 Tire radius-->13.05 inches dia-->26.10 inch


So it will work out perfect for you.

 

Only by a tiny bit. It will not be noticeable to the eye. By the way 235/60 15 came stock on 91-92 RS with the 15" rims.

 

im runnin 205/60/15's up front and 255/60/15's in the rear and so far the only differnce i see over the 235's i had all around is that the back are wider.

 

that's alot of rubber..........why not go 235/55 or 235/50? it will look alot better.

or you could go with some rubber bands like my 295/35's

 

i am running 235/55/16s on my 92 right now, u can go to my cardomain to see pictures, they're all 235.....

On a 15x7 rim, GM offered 235/60r15s as an option. I noticed better handling and traction when I switched from 215/65 to 235/60, both were Radial T/A tires.

 

of course traction improves the wider the tire........that's why i went to a 295!

the 60 series seems high. i guess it's similar in relation to a 245/50. i just wouldn't want such a tall sidewall, more room for flex with 60% unlike a 50% or 55 if they make them.

i've got 235/60's on my gtp and i can't stand them compared to my old 245/50's. to much flex in the sidewall when taking corners.

 

Only if you're into little tiny tires. Those will be shorter than stock, which to most people tends to look funny.

 

I ran 225/60R15's on my old 15x7 camaro alloys.

 

I think if you are very familiar with the way your car handles with the 215s, you might find the steering a little more sluggish due to the extra weight of the 235s. Has anyone else noticed this? My '82 Firebird came with 205 70r x 14 from the factory. I upgraded to 235 60r x 14. I noticed that the car felt more nimble with the seventy series tires. There might not be as much of a weight difference between the 215 65r x 15 to 235 60r x 15 swap though.

Thanks a lot for the help guys. I like the look of a bigger sidewall, and since they are pretty much the same hight, i'm sold

 

well, if you are drag racing you want some side wall flex..... thats one of the things the pissed me off about stupid *** F&F, they all had these tiny profile tires and they are sposed to be serious drag racers?!

 

Last question:

Could anyone tell me the diameter of a 225/60/15 tire? Would it be taller than stock?

Thanks a lot!

 

P225/60R15 = 25.6
P215/65R15 = 26.0
P235/60R15 = 26.1
I notice that some of you might not understand about tire sizes. A 60 series is going to be taller depending on the width of the tire. (205 vs. 255) The 60 is the aspect ratio, meaning that the sidewall is 60% of the width. That's why a 215/65 and a 235/60 are nearly identical in height, yet the 235 is wider.
P235/60R15 was an optional size on '86 Camaro's, but not '91-'92's that I've ever seen, although they work fine. This pertains to the 15" wheels, as I know P235/55's were stock on the 16" wheels. One other thing, if you have 16" wheels, it is advantagious to go to the P245/50R16 if you have P235/55's if you want a better performance tire. The 235/55 isn't made in many of the higher spped ratings that the P245 is made in. The highest I have seen in a P235/55R16 is an H rated (130mph). The Goodyear Eagle HP.
Not to give you a hard time, 1982 chevycamaroz28, but most times when you have a large variance in width from the front to rear tires, like 205 in front and 255 in back, it usually hurts your handling more than helping it. The 3rd gen is made to be a good handling car, and putting the back up high, hurts more than helping. This is a proven fact, not trying to flame you!! I know that putting the 255/60's or bigger might be for looks, or for more traction, so I'm not trying to flame anyone who has the big tires in back on 15" wheels. Everyone has their own style, and our cars wouldn't look as good if everyone kept them bone stock looking!

 

well im not takin it as a flmae so i dont really care but im more into straight line racing and not autocross or anything. my car still handles like it did with the 235/60/15's all around. i just notice a bit more traction then before. and i know by raising the assend up it throws the center of balance off. im not goin for the 4x4 look or anything. im tryin to get my car to look good and also handle great in the 1/4 more then like an autocross course. if i was goin for handleing like on an autocross course id lower the car and put some nice wide tires all around.

 

Cool, Thanks for not taking me the wrong way, but that makes sense for 1/4 mi. racing.

 

I created a simple excel spreadsheet where all I have to do is put in the tire size details, and it will calculate the tire heigth. It works for any rim size or tire series. I just enter different tire sizes and it'll tell me if it's taller or smaller than the tires that I'm running right now.

I'm running 245/60 x 15 no handling problems other than they "hunt" a little bit when the pavement had dips worn in it.
The speedo's about 2-3 mph slow. 15x7 gold center aluminum wheels.

 

I am also running 245/60R15's on the 15X7 firebird wheels, and I like them. I like the way they look, too.
