what is considered "low profile" tires?

i know with low profile tires you will get a rougher ride and "tramlining" may become an issue...

but what is considered "low profile" tires?

i have 235/40/18 tires on my 2003 325i... is this considered low profile?

Yeah...it seems like a 40 is considered by most shops to be low profile.

do you guys find your steering wheels vibrate a lot?

i know low profile tires give a rougher ride but i think part of my problem may be i need to re-balance the wheels (seems like i have to do this every time i put back on my summers)..

how do wheels go out of balance? (from winter storage?)

Tires can loose air over time even in storage. Which can cause your imbalance. I also gave you multiple reasons in your other thread as well.

then wouldn't it be necessary to rebalance the wheels every summer when you mount them?

since every winter they would be losing some air

ive been told this is not necessary

it also depends on how you store them for the winter. If they are sitting upright (like when mounted to the car) if they loose air they can get flat spots where they are touching the ground which could cause some minor vibration.

Tire storage info provided by Hoosier.

TIRE STORAGE
The useful life of a tire, whether mounted or dismounted, is directly affected by storage conditions. Tires should always be stored indoors in a dark, cool, dry room.

DO

1 Remove the tires from the vehicle.
2. Remove the air from the tires and store them on their side in a cool/dark/dry environment.
3. Place tires in a black plastic bag when stored during the "off-season".
4. Make sure the temperature range in the storage location is between 40-90 degrees Fahrenheit.

DON'T

1. Don't store tires in direct sunlight or near electric motors. (Electric motors emit small amounts of ozone.) Tires need to be protected from light, especially sunlight. Light causes ultraviolet damage by breaking down the rubber compounds. The storeroom should not contain electrical welding or any other equipment that could produce ozone.

2. Don't apply any chemical treatments to Hoosier tires. (It's not necessary and may actually damage the integrity of the tire by breaking down the rubber properties of the tire.) Tires must not be allowed to come in contact with oils, greases, solvents, or other petroleum products that cause rubber to soften or deteriorate.

3. Don't store tires in sub-freezing temperatures for any length of time. (The rubber can freeze and may crack as a result.) (Top)

+1 on 40 - is the mark on considering it a low profile
