Can u run a 195/50/15 on a 15x7 or will the rim stick out from the tire. Thanks for your feedback

 

Tire manufacturers specify a range of approved rim widths for each model and size of tire. In most cases, 7 inches is the top of the range for 195/50-15 tires. That means that the tire will appear "stretched" onto the rim (or, as you put it, the rim will "stick out").

If 195/50-15 is the best 15" size for your car (like it is for most Civics), you might be better off finding a 15x6 rim that you like.

 

Yes, you can run a 195/50/15 on a 15X7, but it will be stretched. IMO, a 205/50/15 tire size would be more appropriate for both the wheel size and the stock rolling diameter (to keep your speedo accurate).

Actually, the 195/50-15 is closer to the stock rolling diameter (to keep the speedo accurate) than the 205/50-15 is.

Most Civics have 175/70-13 or 185/60-14 as stock tires. Here's how the outer diameter (which determines speedometer accuracy) compares with each:

175/70-13 stock
195/50-15 +0.14 percent
205/50-15 +1.88 percent

185/60-14 stock
195/50-15 -0.28 percent
205/50-15 +1.45 percent

I was lookin' to get a set of 215/45/15 for some 15x7 rims on my 'Teg. I'm sure they'll fit and work, but would I be pushing it too much?

That's not a good size for an Integra. Not only are they too wide, but they're much smaller (3.5 percent) in outer diameter, so your speedometer and odometer will be off by quite a bit.

The 195/55-15 size (stock size for the GS-R and Type R and I think Special Edition models) on a 15x6 rim is perfect, and there are a lot of excellent tires in that size in all performance and price categories. If you got stuck with 15x7 rims, which are really too wide for an Integra, you can either mount 195/55-15 on them (most 195/55-15 tires are approved for rims up to 7" wide), which will maintain the accuracy of your speedometer and odometer, or you can use 205/50-15, which will still have some speedometer/odometer error (1.6 percent). (In case you're wondering, 215/50-15 is a good match in outer diameter, but they're not recommended because they rub.)

 

Yo thx for the info. It was super helpful. Helps me decide to just stick w/ the tires i got. But just wondering, I don't know too much 'bout AutoX 'n road racing, but like, if 195s are perfect for 'Tegs, then would 'Tegs be at a disadvantage to other cars runnin' wider tires like the RSX or like even 240s 'n stuff, assuming that the driver's abilities and suspension setups are roughly the same. I've seen some race 'Tegs w/ 225 series tires in the front and wonder how it can fit.

I know quite a bit about autocross and road racing. (I've driven in close to 200 road course events.)

There's a common misconception about what makes a car and driver fast. People who have never driven in these events think that the most important factors in lap times are something like this:

1. Power
2. Suspension settings
3. Tire width
.
.
.
73. Driver experience and ability

The true factors that make a car and driver fast, as people who are involved in the sport know, look more like this:

1. Driver experience and ability
2. Driver experience and ability
3. Driver experience and ability
.
.
.
17. Tire compound (tire model)
.
.
.
29. Power
.
.
.
42. Suspension settings
.
.
.
57. Tire pressures
.
.
.
72. Tire width

I'm not trying to pick on you, I'm just pointing out that this is a VERY common misconception that many people share. The point that I am making is that it's all about driver ability. An experienced driver can rent a compact car at the airport and blow the doors off a novice driver in a big-bucks sports car. This is true for autocross as well as road course events. And even when you get past that, and look at car factors, tire width is an EXTREMELY minor factor compared to many other aspects of the cars. For example, stock size R compound tires will be much, much faster than street tires that are 20 mm wider.

If you're thinking about driving in autocross or road course events, that's great! They're a lot of fun, and there are a lot of ways to enjoy our cars. When you first start out, tires and brake pads and such aren't going to make any difference whatsoever in how well you do. So as a beginner, your best bet is to take your car out the same way you drive it on the street (okay, maybe with fresh brake fluid), with no special preparations. You'll still have a lot of fun doing it. It will keep your costs low, because you won't have to spend money on changes that aren't going to make you faster at first anyway. And you'll see why it's not as easy as everyone thinks it is. (Everyone goes to these events for the first time thinking, "Oh, I've driven fast on the highway, I know I'm going to be the best one out there", then finds out how important the experience factor is when experienced people in slow cars turn better lap times.)

If you drive in these events a lot, and build up a lot of experience, then your lap times will drop by full seconds, and you might even get competitive, to the point where you are doing well and close to winning your class. Only then will you want to consider making changes to your car to gain those last few tenths and even hundredths of a second. And yes, some of the autocross champions may be driving overwide tires and such, but only because they've already done about a thousand other things to their cars that were much more important than the width of their tires - everything from gutting the interiors of their cars, to switching to track-only tire models specially made for autocross, and a whole bunch of other things.

Hey don't even worry 'bout that at all. I gotta thx you for puttin' this info out. Ya I'm gonna get into autoX or some road racing events as soon as I pay off this semester's fees and books 'n stuff. I'll e-mail this thread to myself so that I'll remember.

 

PY's DC with 195x50's



mine with 205x50's



notice the diff...hope it helps
