1.5 Roadster Tire Thread

[vfx]

As not to highjack the 2.5 and Sport tire thread.

With a 1.5 there is no "tire learning" mode so tire choices are limited as to diameter and other factors.

What are you trying and how is it working?

[vfx]

I recently tried Falken tires only on the rear. I needed rear tires real quick.
$341 for both installed.

The bad side:
They are more squirrely than the stock tires that I had been exclusively using to date.

The TC light does come on all the time on deceleration and basically there is no regen. Very interesting and I don't like it. If you release the accelerator at 55mph the regen kicks in when the car coasts down and hits 20mph.

By the way. One guy at a shop told me my "Lotus" was required to have run flat tires and would not install anything but those.

I have air settings at 30F 40R as Tesla recommends.

Does it make sense to have version 2.0 covered by this thread, or by the 2.5 thread, or is there any reason for it to be separated by itself?

1. Garbage, of course, on the first item.
2. Try reducing the delta between front/rear pressures. I am thinking 32-33 F and 35-36 R.

Agreed if the 2.0 is different enough then it should have it's own thread.

My guess was that 2.0 and 2.5 should be included together. Are there any known tire related differences 2.0->2.5?

I agree... I don't think there is any difference between 2.0 and 2.5 in terms of tires.

I just don't know about 2.0 and 2.5 cars. I would imagine the issues related to tires are:
Adjustable suspension (1.5 it was was not offered but I would guess you can now get it installed.)
VDS firmware being able to "learn" new tires (not on a 1.5 screen)

slightly tire related.
mudflaps
new wheelwell material

Anything else? What applies to 2.0 cars?

[Doug_G]

Well, the 2.0's have the learn tires feature. AFAIK the 2.5 changes are mostly cosmetic. (Aside from things like improved PEM, which some of the 2.0's have anyway.)

At Charge It!s recommendation (thanks C.I) I adjusted the tires to 32F 36R [outside temp was 80] this morning. I drove 50 miles one way and notice little or no change. A bit less squirrley and maybe some regen but negligible.

On the way home 3 hours later [out temp was 90], I was in classic LA stop and go traffic. Regen was working below 20 mph but as I went along I noticed it was working above 30 and then above 40. By the time I got home regen seemed to be back! TC light comes on very little (still more than stock tires) so everything seems back to normal (ish). Am I grateful for LA traffic here?

I'm curious if it was the air adjustment or if it would have learned the Falkens in time. Thanks again to (C.I.)
