holy flat-spot Batman...

**TRM** · 01-10-2004, 10:00 AM

so the STi was sitting in almost sub-zero temps for a few days...and these RE070's had major flat spots.

it went away in under a mile, but felt rather interesting.

anyone else experience this?

Billy_Talent · 01-10-2004, 12:16 PM

No, but it makes sense; they're very soft tires.

Ambros · 01-10-2004, 02:19 PM

Soft tires?

The RE070's seemed really really hard the last time I checked...

Hard?

Scuba_Steve · 01-10-2004, 03:17 PM

The side walls are hard the rubber is soft.

RadarOnPaws · 01-10-2004, 06:47 PM

Yeah, the rubber is VERY soft. Rocks stick to the tires because they are quite gummy.

FIA-WRC · 01-10-2004, 07:15 PM

Yes the rubber is soft but flat spot due to cold temps? It doesn't make sense because shouldn't this be more likely when it's hot out?

Sounds like the old Nylon "thump". It was pretty common when radial tires were first introduced and was attributed to the Nylon cord in most tires taking a set in cold weather. The makers soon got rid of it for most tires but the very conformable RE070's might be especially prone to it.

They used to warn drivers to take it slow until the thump went away because of potential loss of control at high speeds.

I experience this if I leave my car sitting for a while... Flat spots are typically caused when you park a car with HOT tires on a cold surface. Once the tires warm up again, it typically goes away.

CloNeGTS · 01-11-2004, 12:13 PM

I've experienced with my Pirellis in the last few months....so it's not just the RE070s.

I have this problem quite a bit. Doesn't matter what the temp. Just if the car sits a couple of days. It really gets interesting if you move the car just enough so the tire doesn't sit on the same contact point constantly you end up with a whole lot of little flat spots. thumpa thumpa thumpa

qbushido · 01-11-2004, 03:12 PM

yea it happened to me yesterday. went away before the car was even fully warm.

inxs · 01-11-2004, 07:33 PM

mine does the same but only when it is cold outside <40 i just keep the speed down for the first few miles and it goes away.

ERacer · 01-12-2004, 11:02 AM

Same here cold or hot. Goes away as soon as the tires get some heat in them.
