Hello,
I need to replace the 285/30R20 tires on my 04 xkr rear BBS wheels (Detroit style) with prob Michelin or continentals. Can any of the tire place do this, places like pep boys etc or do I need to go to the dealer? I have the adapter to inflate the tire, that's all I know is specific about these, but I was wondering if mounting the tire on these wheels require any other specific tools that a Firestone or a pep boys wouldn't have.
In other words is the process the same on these BBS wheels besides the inflation adapter?

Thanks

 

I just got new tires myself on my BBS 20's (Les Schwab) and didn't even think to ask and they did it no problem.

 

Oh cool. Which one did you go to in LA?
What brand? I'm thinking Michelin or continental. Mines got hanckok not familiar with that brand.

 

Also question, do the threads need to match front and back tires? Is there any constraints on terms of front tires and back tires threads?
For eg front threads like .....vvvv .... and back threads like ....~~....
Lol I hope you like my symbols to rep threads.

 

Probably stating the obvious to a tyre guy but the tyre fitting to these rims is from the inside of the wheel. Just mention it to them in case.

 

So, I have these wheels as well and I was wondering: the spokes are asymmetric (one edge of the spoke is "aerodynamic", the other more perpendicular). But all my four wheels have the same direction of the spokes. This means, when I put them on the car the leading edge on the left-hand side of the car becomes the trailing edge in the right-hand side.

My question is: are there different BBS Detroit left and right models and I happen to have only one kind?

 

I'm confused. What does that mean tire fitting is from the inside?
Thanks.

 

Usually you put the tire in the machine so that the hollow side is down and the spokes face up, i.e. what would be the outer side when mounted on the car is facing up. Then you install the tire.

With these rims you put it the other way around in the machine, i.e. what would be the inner side when mounted on the car is facing up. (The machine has to have special clamps that can "squeeze" the rim from outside, in contrast to expanding inside the rim to hold it). Then you install the tire.

If you attempt to do it the standard way you will damage the protective chrome ring.

 

Good to know. Thanks a lot.

 

Only one spoke design. There is no specific left or right design.

 

I would also echo the concern for the trim chrome rings. They are expensive to procure, and likely to run out at some point. I would definitely run this by the shop manager to make sure they are comfortable working on this, and even honest enough to tell you if they are over their head. Also give them the option to come back when their best tech is on shift.

 

I wonder if exotic tire shops would have these clamps. Are they common or more like pretty rare?
Thanks

 

Do you mean because they hey damaged every time there's a tire change?
Thanks

 

I would not expect it for a shop with the right equipment and properly trained tech. Best is to go to a shop and ask...

 

Alexander the What?

I have 20" "Montreal's" on my 2005 XKR.....Front Tires are: 255/35-R20 - Continental Extreme Contact Sport DW and cost $243.00...Rear Tires are:285/30 - R20 Continental Extreme Contact DWS and cost $201.00..(Front Wheels are 9" Wide and Rear Wheels are 10" (Staggered)

BBS Wheel Tips:
Tip #1- Always carry a Screw-in Air-Pressure Valve - (To check Air-Pressure)
Tip #2- If you don't have one order a Air Valve Accessary Bag ….(It has 2 or 3 Air Valves, a Screw-remover tool and a couple of Screw Caps)
Tip #3 - Get a couple extra Air Valves..Just in case one of yours gives way....The one in your Wheel could be almost 20 years old! (Think about this)
Tip #4 - Always ask the Tire Store Manager if they have the knowledge and Equipment needed to change Tires on a BBS Hub/Wheel...……….

And Yes! Ask the Tire Store to mount them from the rear of the Wheel....to protect the SS Curb Guard.

Thank you for the information.
I have the valve that I bought recently. Just one though. Don't have the screw remover though. But a simple flat should do no?
Thank you

 

Alexander,

You should look for a couple Air-Pressure valves....I've had (2) broken by the Tire Machines. If I hadn't had 2 extra at these times, I would not have been able to air up the Tire! I guess I would still be at the Tire Shop....and yes! a plain old screwdriver will work but that's not the Point!

I understand it's not the point. You're right, it's good to have a spare. I was saying a flat screwdriver would do only because you can't get these kits anymore with 2 valves, cap remover, extra caps etc.
I could find the adapter as new edition but that's it. Definitely should get a couple of adapters just in case though.
Thanks

What Billy said. I had my tires mounted by an independent jaguar specialist that I trust. A regular tire shop could probably do it, but I was afraid that they'd forget to return my inflation adapters. I figured better safe than sorry.

You can get the extra valves and caps from either Dave Roche @ DCR, or order them directly online from PW motorsport here: https://www.pwmotorsport.com/pr,130,...bs-valves.html

You can also get extra adapters, bolts,etc from either as well. I had one of the caps fly off a while back, so I can attest to the value of having spares.
