The tire shop told me they couldn't mount my 255/40/17 Falken RT-615s onto my BBS wheels. Said the sidewalls are too stiff and they can't get the right bead. I know there are hundreds of people here running the 255 RT-615s... If anyone else has had trouble getting these tires mounted, please share your experience. thanks

 

Sounds like that tire shop is a joke. Go to one that has experience and not some 18 year old kid who has worked there for 3 months. I do know people run 255's on stock wheels but I would not go bigger than 245. You will sacrifice handling with those tires but should have better straight line traction.

 

I couldn't get to my first choice tire shop today because the street is closed for a parade..

 

I used to do tires for a living. I could mount 255's on stock wheels, but you may also consider the possibilities that they WONT, not that they can't.

After a while of liability suits by people with lawsuits, we stopped mounting anything but the Manufacturers approved list of tires.

Even though it will fit, Mitsu does not approve anything bu 235/45R17's on stock evo wheels, and I forget what the regular lancer's get.

 

Thanks for your post. I completely understand CANT vs WONT. But they did try one and they told me they even took it up to 60psi with no luck

 

Not to be pedantic, but I don't agree that you sacrifice handling with those tires, but rather responsiveness. The ultimate level of grip of the 255's is just as high as the OEM Yokos.

 

Kitty-Kats! (You know what I mean, it starts with a P)


I've had to take tires up to a buck, buck n a quarter inside a cage.....again, probably some 18 year old kid thats been there for 3 months.


Just gotta find someone who has done it a while....its a bit of brute force over tip-toe around it.

If you have a compressor, get a locking valve stem chuck and a 10' hose. Go around the corner of the building, and proceed to take it up until you hear it pop.

Dangerous as hell, but I've had ZERO tires blow up in 10 years doing it.....

Make sure you remove the valve core before you do this, as soon as the bead pops you can yank it off and take it down to a safe pressure.


A couple of things however, you don't have a bit of lube (soapy water will work ,though you dont want water trapped in the tire)....tire lube is special stuff if you want it to work right.....


Actually, kinda similar to hair gel.....but a bit of pure dish washer's soap works too, only a couple dribs and drabs.

If you need help, PM me or even email me, I'd be happy to oblige to give you direction. Take care-Feldguy

 

Grip is an entirely different thing. Handling will be sacrificed because of the excessive width of the tire as opposed to the width of the rim. It gives that "buldging effect" where there will now be a significant amount of roll when taking hard corners. Probably won't be noticable to the daily driver but will definitely be noticable once you take it onto a road course.

 

Regarding the width... I mounted 255 Toyo T1S on stock rims without issues before but I always do check what the tire manufacturer suggests for min width and the Toyos are were rated for 8" rims...

I planned to buy the 255 615's next, but to my surprise they are not rated for 8"rims...8.5" min.... http://www.falkentire.com/rt615_sizes.html

 

Just a small update:
I got them mounted. Had to do a little bit of traveling but it was worth it. These Falkens aren't as loud as the Advans

It took the guy 110psi to get them to bead right.

 

My old shop had a special low profile tire mounter. Im sure well known places should have one of these.

 

Oh well. They've lost your business, just find a place that will do it.

 

wow, you guys are brave. 100+ psi!!!!

I work on european cars all day long, and I mounted the Falken's myself.

Let me tell you, they don't have **** on a Porsche GT3!!

 

^ He got that problem fixed buddy

I'll see u tonight at Proccos Dion.

 

I work at Costco in the tire center, and we WILL NOT mount tires that are more than +3% or -3% of the original tires specs for liability reasons. Now, I'm not saying that it's impossible to do, it's jut that some shops are ver strict when it comes to these things because if something happens to the tire/rim, they'll be the ones to blame.
