Plus, I have a new baby coming in a month, and after buying these rims, it’s going to be hard to convince the wife I need new suspension too. I may leave it as-is, or look at seeing if I can trade the rubber in for a slightly higher-profile set.

Update: Well, after humming and hawing about it over the winter, I finally decided to get new tires that have the proper diameter. No place would trade, so I had decide whether it was worth buying new ones. It’s a tough hit on the pocketbook to replace something that shouldn’t have needed replacing, but I found a good deal at a shop here in Calgary, and also found someone willing to buy the smaller ones so I’m coming out close to even.

Stock tire size (above right): 215/55R17 - overall diameter - 26.3"  
Original replacement (above left) : 225/35R19 - overall diameter - 25.2" (over 1 inch smaller! crazy)  
New tires: 225/40-19 - overall diameter - 26.1"

There are a ton of different sizes that could’ve gotten me close, and the 225/40 was the best bang for the buck. My first choice for a replacement was actually a 235/40, but they were simply too expensive. It seems that they’re just not common enough. Another option was a 245/35, but I’d still be over a half-inch smaller diameter.

I’m getting them swapped tomorrow, so I’ll update with pictures afterwards. I’m looking forward to seeing another inch of the wheel well disappear. :biggrin:

PS - I also decided I might as well upgrade the quality too, so from the generic Nankangs that were too small anyway, I went with some Kumho SVT KU31s, which seem to have some pretty decent reviews.
