Questions regarding to the 991 to my fellow drivers.

![Question](https://rennlist.com/forums/images/icons/icon5.gif)
Dear all,
I recently purchased a 991 C2S, with all the performance options except the sport exhaust and the PCCB.
While doing some break-in driving, I noticed a few issues.. I don't know if they are considered normal "characteristic " of the car or the car has a discrepant condition..
1. When I try to make U turns, with steering wheel turned to the ends, the car moved with a very jerky motion.. (it reminds me of a 4X4 jeep with differential problems)
2. After driving, I would smell strong rubber odor from the rear wheels.
Please advise..
Oh, the car only has approx. 300 miles in the odometer. It was ordered new, with 17 miles on the odometer.
Thanks in advance.

The important point is nothing is wrong with your car.
Other than that, I'm stumped. Mine certainly isn't doing that, though I admit to breaking in the tires in the first 200 miles pretty thoroughly.

Thanks for your insights, Gary.
I've been driving it very mildly. smooth acceleration, never exceeding 4000 rpm, etc.
The car does jump side ways when turning the steering wheel to the locks.. This is the first 911 I've driven, perhaps I'll have to get used to that.. I've been driving the E46 M3 and the E92 M3 for a few years now, both cars turn very smoothly in tight corners..
The rubber smell is more of brunt rubber odor. it just reminds me of when my old jeep's differential got stuck and would not drop from 4WD to 2WD, the wheels would not turn at the same speed when cornering, so tires would skid and chafe on the ground, which produces brunt tire smell. (sorry for the jeep comparison, it is what I can relate the most..)
Thanks again.

I really think your tire smell is just new-tire smell, but it certainly should not continue beyond 600 miles or so. Bug your dealer if it does. Damn, that's a beautiful car. Here's mine.

The rubber smell is typical of all 911s. Rear tires are very close to very hot parts in the rear. Besides it may not be rubber as it could be, and probably is, hot cosmoline - the brownish coat Zuffenhausen sprays on the lower parts of the engine and transmission to protect it from salt corrosion during the Atlantic passage. Some cars have more than others, I guess it depends on the time of the year the car is shipped and/or ship carrier.

I did get that new burnt smell coming from the rear, but was quite different than burnt tire smell. Smells good to me. Although when the 996 was new in May of '98, it smelled much better than the new burnt smell of the 991S.
But the interior smell of the 991S is . . . take a breath . . . oh so nice!

I have owned several Porsches in my life, but I vividly remember my last two, both my 2009 997.2 Carrera and my current 2013 991 Carrera S both have the steering issue at full turns and the rubber smell. Nothing is wrong with your car. Thought I had a problem with my 2009, dealer checked and was the cosmoline. Just got used to it.

jerky response on hard turn is normal as is the burning smell. the smell will dissipate however, the jerky response will not unless you put 19 inch wheels on the car. My 20 inch wheels were switched over to 19 inch winter wheels and tires and presto, the jerky response (that i only noticed in my driveway) is gone.

Guys! It's the super wide tires and steering angle....stop worrying! Doesn't happen at higher speed, let's be thankful...there for a good reason...Thank goodness we don't drive these cars under 10 mph, most of the time
