Loose and sloppy handling.

EP11 · 03-20-2014, 09:58 PM

So on my 07' 335xi I recently put new 19" CSL replicas and tires. I'm quite happy with how it looks however it seems like now my car feels very loose at high speeds. Whenever I'm on the interstate and driving at around 70-85 mph and want to change lanes it seems like as soon as I want to straighten back out I'm fighting the rear of the car for control. My car was also wearing the inside of the original rear tires so I did have it aligned recently so I doubt it could be alignment. I have however also noticed when I'm driving on the mountains that when I'm going around a turn and ascending at a good speed my traction control light starts flashing sometimes. I loved the way my car handled on the interstate on the stock wheels, even though I didn't particularly like how they looked. I really want the looks of these CSLs but don't want to sacrifice drivability and control of my car for it. Anyone have any idea what the problem could be? And how to solve it?

Thanks in advance.

You running staggered wheels?

EP11 · 03-20-2014, 10:16 PM

Yes. 8.5 (235/35ZR19) and 9.5 (275/35ZR19)

ktran · 03-20-2014, 11:38 PM

You should go with 235/35/19 and 275/30/19

pits200 · 03-20-2014, 11:49 PM

Ya your issue is your outside the 1% threshold I think. If that is the case you need to take the tires off now since you're damaging your transfer case

EP11 · 03-21-2014, 07:56 AM

No my bad I made a mistake, I have 275/30ZR19 in the back. Not 35s

T0NE*F32 · 03-21-2014, 08:30 AM

what brand are the tires?

EP11 · 03-22-2014, 08:47 PM

They're Kumho Ecsta SPT

dsjr2006 · 03-24-2014, 12:39 AM

How many miles? Maybe time for suspension maintenance/replacement/upgrade..

ashmostro · 03-24-2014, 02:12 AM

I wouldn't dismiss alignment issues so quickly- shops can screw up. Have it re checked by another shop.

Very true. I've had this issue before, at the mileage most '07s are it's probably time for maintenance on many suspension parts too.

gzim335 · 03-24-2014, 04:44 PM

always check tire pressure.

dsjr2006 · 03-28-2014, 02:50 PM

Did you have Runflats before too?

SDemetris · 03-31-2014, 12:46 PM

Get of aligned and your suspension set again. Your geometry changed with wheels and it will act goofy until its fixed.

ashmostro · 03-31-2014, 06:33 PM

Demetris brings up an excellent point. How much did your offset change up front from stock?
