I've been looking online at new tires for the TR6 5.5 inch wire wheels on my '62 TR3B for a couple of weeks now.

Most of what I've been looking at are 185/70 x 15 for the wires.

Definitely slim and/or expensive tire pickings out there.

But lots of choices, if you slide down to a 185/65 x 15 profile. But in several recent tire threads here, I haven't seen anyone suggesting that profile as an option. Must be a reason?

I've read that the 185/70 profile combination matches the original tire/wheel set up within 1%.

How far off will my speedometer/odometer be with a 185/65 profile?

(Not even worried about the spare, I have a 4.5 inch 48 spoke wire wheel for that and will pick up a 165 x 15 radial as a spare, to replace the bias ply that's in there now. The spare tire area on a 3B is a little "roomier" than on the older cars.)

According to this tire size calculator, the difference between stock and 185/65-15 is about -3.6%.

Which, assuming your speedo is perfectly accurate otherwise, would mean it would read high by about 2.5 mph at 70 mph. Hardly enough to worry about in my book (but I'm the guy running 205/55 tires).

Hello There: Perhaps this subject has already been posted but here goes anyway. Moss motors is having their sale going on at the moment and I want to buy chrome wire wheels for my 57 tr3. Looking at the moss web site I see that they are listing MWS dunlop style wheels. In doing some research, MWS stands for motor wheel service company with their company address listed in England. My question is: Are these the wheels that are built in India and are they troublesome or Junk? Should I even consider buying these wheels or has anyone have any experience with this product? Should they be checked for being True before mounting any tires on them? Any information would be helpful with my decision. Thanks.

Bob, you might want to start a new thread with this new question. You'll get more readers that way, and possibly even some more answers.

Sorry I can't answer directly. I bought mine from Dayton in Ohio through Valley Wire Wheel (in Van Nuys, CA). Whatever the other merits, Dayton makes it clear where their wheels are made; while I couldn't find any direct mention on the MWS website, except for the history entry
"1982 : First batch of wheels are produced by Wheels India Ltd"
