Whats a good 255/50/17 tire that I can put on my bonne? Wanted kumho supras but i have a feeling i should go with something a bit more for all weather. Looking to spend around ~450-500. TIA

There is only one (1) all-season performance tire in the size 255/50R17. It is the Continental ContiExtremeContact. According to Tirerack.com it is rated second (2nd) in the Ultra High Performance All-Season category and is priced at about $122 US.

I am going to go out on a limb and guess that you picked this tire size because it is the closest to your stock tire size of 235/55R17. I just hope you are not keeping your stock rims.

What is wrong with the stock rims?

Absolutely nothing is wrong with the stock rims. They look great.

What is wrong with this scenario is putting tires with a 255 mm width on those stock rims. The problem does not arise because of the diameter of the new tire size (it is arguably as close to stock as you are going to get), the problem arises because of the width of the new tire. The new tire width would cause excessive overhang when mounted on 2000 stock rims causing premature sidewall damage and, quite possibly, worse handling. Traction and braking will improve, because the area of contact is greater, but handling will suffer. It’* a judgement call really. For me, I am going to stick to the stock tire size.

I thought you were saying the stock wheels were ugly or something. I completely agree that the stock tire size is fine. It isn't necessary to go any wider. I didn't check the tire sizes or anything to make sure, but if these tires are much wider than the stock tires, then they should definately not be run on the stock rims. I understand that, and I hope anyone planning on changing tire sizes does also.
