I think I may be suffering from tramlining with my 19" alloys. I think this is a common problem after such upgrades on any car?

I only really notice it at speed and it feels a bit like there is strong wind and i'm correcting the steering from left to right a lot. I don't know how much i'm imagining it to be worse than it actually is though!

Anyone else suffered from this and any tips on what I should try to fix it? It's certainly not dangerous, just a bit annoying.

I've recently gone over to 19" non RFT's, can't say I've noticed it any worse than with the 18" RFT's

My E92 on 19's tramline less than the company 320d E90 on 17's, what pressures you running?

Going to a larger wheel may cause an increase in tramlining, especially if the width of the wheel has been increased. If the width is the same, there should be very minimal change as the only difference will be in sidewall compliance. A move from an 8J 18" to 8J 19" shouldn't be as dramatic as you're making it sound.

Have you changed the tyre manufacturer/model? This will have a huge difference in the way a car handles - some tyres are much more prone to tracking every nuance of the road. You might also want to get an alignment done if you haven't had one done in a while - you may find that you're running a bit too much negative camber (as the car settles down on the suspension over time) and this will lead to an increase in the tramlining sensation.

Also check your tyre pressures - on 19" NON-runflat tyres a good starting point is 37psi front, 39psi rear

Wow - thanks for the fast responses!

The width has increased from 205 to 235.

I suspected I would need an alignment and tracking done, I naively thought that the wheel-base, the place I bought them from would have done this though. I presume not?

The make of the tyres has changed from Bridgestone to Toyo Proxys. I was actually going to ask what PSI I should be running, I haven't actually checked since they fitted them - again am I being naive to think they would set them up correctly after fitting? :-)

Regarding pressures, do a seach you'll find various threads. I'm running mine at 40F & 42R

I assume you have wider front rims?

I'm not a guy to jump on the alignment issue, as first move. If original tyres were wearing evenly and the steering was precise, look at pressures first, IMO.

You'll need to experiment with pressure. Start with 1 psi up and down on suggested pressure. Sense the changes. If you run on the softer side, to reduce tram-lining, remember wear rates will likely accelerate on the shoulders, even if alignment is fine.

Thanks Pete,

Regarding wear rate, is it logical to expect larger tyres to wear quicker than say 16" tyres? In my head when I first saw the tyres I thought - christ there's not much to go at with them!

Tone,

would you mind telling me I should be running (pressure) on my 19' RFT on an e90, Thanks

Does it not say on the sticker on the drivers B pillar?

It does but all air pumps are displayed in psi and the b pillar quotes in lbs, very confusing

Door card states 2.5 bar front 3.0 bar rear on my E92

bar not lbs. Either way how do you convert bar to psi?

Multiply the bar by 14.5

A lot will depend on what tyre you are running. Typically you will find it harder to get the mileage, if you use the handling properties enthusiastically.

Faster/harder cornering will knock the front outer shoulders off pretty fast, "you don't get nowt for free" as they say.

You may be tempted to lower the pressure to reduce tram-lining and the odd road follow, which typically the lowest aspect ratio tyres give, but that does mean you sacrifice on the wear rate.
