Re: Tyre n Rims
Most rims do carry some form of specification e.g. 18 x 8.5J, 17 x 7.5J . The first digit specify the rim diameter in inches i.e. 18 = 18 inches, 17 = 17 inches. The second digit represents the width of the rims i.e. 8.5J = width 8.5 inches.
If you like wide tyres, than go for the 8 or 8.5J specs which meant you need to shod it with 225 or 235 tyres.
BBS got quite a good range for Bimmer 3ers... go to those bigger rims showroom and check things out before committing. BBS is also known for their light weight (advantages as highlighted by TripleM).
If deep dish is what you are looking for, then you need to look into the direction of Hamman.. those rims are really pretty but you may need to roll your fenders (or wheel arches). They are also less common and pretty hard to find.
Tyres are very varied, hence if its just for daily drive, any HPT would be sufficient. My personal preferences are wet tyres (usually comes with bigger block design and deep passages to displace water). Advantage is that they are less prone to "aqua planing" which I felt is crucial in wide tyres application. (Wide tyres have more surface, less ground pressure, therefore more prone to planing and spin in wet weather).
Wet tyres have their disadvantage as they are normally more noisy, especially if you have lowered and stiffen your suspension.
"Wheels" are your only connection to the road and it does command a little more consideration. You will have to weigh and trade "comfort" "economy" "performance" "durability" in your choices..
The easiest approach is to prioritize.. so you need to identify your criteria.
1. How do you normally drive and some consideration of the driving environment.
2. What are the next criteria you are more likely encounter beside the above.
From here, you select a tyres that most suit your item 1 with some veer towards item 2. Happy hunting.
