Replacement Tires

It is nearly time to replace the original rear tires.

I haven't seen any comments lately from owners that have replaced the rear tires and was curious what make you choose, size, etc. I would also be interested in knowing WHY you made the choice you did and what your thoughts are now that you have driven on them.

Thanks

The Tesla Motors Club www.teslamotorsclub.com has extensive threads for tyre choices. (In fact most roadster discussion happens over there, not here.)

For myself, I had some Kumhos on my Mercedes and loved them. Put the same tires on the roadster and hate them with a passion. I drive faster just to wear them out... :-)

How many miles did you get on the stock tires?
I had to change my back tires at 6000 miles.
Was told this is normal.

I had them replace the tires when they did the first service because they were down to threads..

thanks

That's pretty normal. I only got 5,000 miles out of my rears.

I had the AD07s and replaced my rear tires at 7,700 miles. I still had some tread left but they were starting to get noisy. I think 5-7 thousand miles is normal but you can get more depending on how you drive.

The wear bars were showing after 4,400 miles with the stock Yokohama's. I guess I was having too much fun driving it. I replaced them with Continental ExtremeContact DWS which were 1/2 the cost and are supposed to last 3 times longer. After 3,600 miles they still look great and they stick nearly as well as the stock Yokohama. No problems with traction control on my 1.5.

DHrivnak: You had the AD07s? Wow. You were having fun=) Are you using the 195s on the front then? I don't think they come in the exact front tire size.

The stock fronts are still the AD07's that are 175/55/R16. They still look good after 8100 miles. I am quite sure the intial owner did not change the tires as the car only had 1000 miles on it when I bought it.

That size will be hard to match in the future from what I hear.

Yeah. Actually, the AD07s are the only tire you can find that fit exactly. Other people are using tires in the 195 size I believe and are not having major problems as mentioned in the TMC thread.

I have had the folloowing tires on my Roadster for about 2,500 miles, now, and I like everything about them.

Front: Kumho Ecsta 4X KU22 195/50 ZR16 84W
Rear: Michelin Pilot Sport AS Plus 225/45 ZR17

The diameter ratio is the same as the ratio for the original Yokohamas so the regen braking works as it should. This is my second set of the Michelins on the rear. I had 38,000 on the last set and only changed them because I'm doing this Route 66 drive and wanted new tires for the drive. My guess is that I would have easily got 45K out of that set. However, I don't do a lot of racing.

I switched to 195/50-16 on the front and have Conti DWS all-season tires all the way around (so the car could be useful in Cincinnati winters). When I first put them on, I was a little disappointed in their lateral dry grip compared to the AD07s. But, the DWS are MUCH better in the rain, especially with regard to straight-line stability when the AD07s would skitter about and need constant correction.

YMMV

Don't take "all-season" literally. In snow they don't compare to actual winter tires.

Some do some don't. Nokian severe service WR-g2 all seasons are as good or better than many winter tires. Unfortunately, they don't come in Tesla sizes (hopefully that's a "yet"). Most all-season tires are like Brian says--Texas all season, but there are some good ones out there.

It's tread depth; snow tires can throw away stuff that clogs and smoothes lesser channels. You can't have both long highway wear and wide treads, however.

There is more to it than just tread depth (which is mostly applicable when the snow is soft and deep). There is keeping the rubber flexible when it's cold, having the belts support the tread blocks properly, being able to wipe away the film of water that occurs when ice is close to freeings, etc.

True 'nuff, but snow tires have the edge in all those respects. Anywhere (like most of Canada, with the exception of SE British Columbia) where there is serious snow and cold, all-weathers are a dangerous compromise. Save money on seasonal tires at your peril!

Where there is a real winter, you generally want two sets of wheels and tires. However, all but the best snow tires are going to be no better than the Nokian WR-g2 (and a few similar tires) for winter conditions.

Some are quite a bit worse.

I use the Yokohama A048's on my Roadster S. I tried a few alternatives, but they don't have the traction. Note that the AO48's only last about 1,500 miles (at least with my driving.)

When it came time to replace my rear tires, i wanted a set that has good traction, better tread wear than the stock tires and costs less. I got a pair of Michelin Pilot Sport A/S Plus at Sears on sale ($480 installed vice $800 from Tesla). What I immediately noticed was that they seem to perform as well and are much quieter (especially above 40mph) than the stock tires. I can actually use a Bluetooth phone with the Apline radio in my 2.5. With a UTQG of 500 AA A, I highly recommend them.
