Stretching Tires

[412chris2g]

Hey guys so I plan on buying some new rims.. I currently have some rims on my car and the Lip Or dish or whatever you want to call it is pretty nice I like how it wide it is. Now when I get new rims am I going to have to stretch the tires again or will the rims still have a nice lip? I'm not sure if the current rims on had the tires stretched or not but he's a current pic.. Thanks!

Nobody can answer that question with the details provided. Include information such as offset, width...
Stretching all depends on the size of rim, and the size of tire being put on that rim.

I see. My car is currently in the shop. Don't have specs on me.. I just heard that in order to get a lip like mine or bigger you have to stretch.... And I don't know what is true

"They" probably told you that because of the typical rim width and offset that comes with the deep lip rims. I did a quick search and the smallest offset/rim width I was able to find was a 17x9 with a +25 offset. I can't say much on rims past +38mm offset because that's the most I have ran (evo rims 17x8). Hopefully somebody else will chime in with a little more offset/rim experience.

Good luck

Why anyone would stretch tires just baffles me. There's no reason for it if you're utilizing a proper wheel setup on your car. There are plenty of ways you can correct for various offsets and widths, even if they aren't commonly used on the DSM platform. You may need to add spacers or coilovers to get the correct backspacing and ride height for a given wheel setup. So, if that's the case, do it.

I'm getting ready to swap in a set of Work Meister wheels that have plenty of lip. You don't need to stretch tires to run a wheel with a lip. You need to set the car up properly with matched wheels, tires, and suspension in order to get an aggressive look that's still functional. If you're running a tire that has less tread width than the rim is wide, you're wasting width that could otherwise be used to improve handling. People who run wheels that are 9" wide wrapped in a 205 series tire are doing it wrong, IMO.

I feel like you're asking a question with two independent answers. Your "rim" choice will determine how much lip you have. The width of those wheels determines what size tires you need, and your choice of tire determines whether or not you will stretch them over the given width of the wheel.

So what exactly is your question?

But it's cool!

That's kinda my point. At no time should you need to stretch tires to make them "work". There are only 2 reasons I can ever see that you would need to stretch tires: 1) You set your car up improperly and don't have either the wheel spacing or suspension clearance required to run a given wheel/tire combo or 2) you're going for that hellaflush look and doing it on purpose, which is absolutely retarded...In my opinion of course.

Want proof? How about a Galant VR-4 on Rota Grid 17x9.5 with hoosier A6 275/35R17 tires. How much stretch do you see there? BTW, the owner of that car primarily autocrosses it, so that setup isn't for looks.

As if stretching tires wasn't bad enough, this guy is stretching a set of Nankangs.

Whoever mounted that tire and let it leave their shop should be shot in the face...Twice.

Ok I just wanted to know if I had to stretch tires to get a lip. That's what I was told...

I'll give to you a lip to be proud of

Chris, after re-reading your initial post, I must comment--the tires themselves have nothing to do with the wheel itself in terms of "lip/dish". That is all dependent on the wheels specs and design.

Think about it--how is the tire gonna make your wheel magically transform and evolve some more dish? Now if you are taking about the exposed part from stretching, that's a different story but from your post, that's what I understood.

So the offset and rim size determines lip?

Yes--here's a few diagrams for a quick reference; notice that the lower the offset the wider the outer lip/dish will be: Note: a +45 offset is considered HIGH while +15 is considered LOW.

HOWEVER; realize and take into consideration that the design will also play a factor--is this case the wheels have less lip but still retain the "concave" from the lower offset: NOTICE* disregard the numbers here as they are meant for ATV purposes--I wanted to use the illustration to show that the dish/lip is dependent on design opposed to just specs*

And the last thing I can share from my experience, is that wheel specs in general can alter everything--like such: Fronts have a lower offset of +30 offset (18X9):

Yet the rears are +38 offset but have a MUCH wider lip/dish due to the fact that they are 18X10 opposed to 18X9:

Just a little food for thought--I'm no expert by ANY means but these I have learned from experience in the small amount of time I been "modding" my cars. GL!
