Tires for 19" wheels are not that much more expensive than 18" if you know where to look. I actually got better tires and lot cheaper than I would have if I went with factory-spec'd tires when I had 19" wheels with my previous car.19s look amazing, until you have to buy tires for them.
Part of the reason I went with 17 inch wheels. CHEAP TIRES and more forgivingThat might be true, depending on what brand tire you buy. If you get cheap, Chinese made tires, then it’s no big deal. But if you want ones that last a long time, like Michelin or Continental, be ready to pay.
I can get some cheap Uniroyals for about $125 ea from where I work or if I go with decent Toyos or Pirellis they go for about $168 ea to $192 ea. Definitely a lot less expensive now than when that size was limited to certain brands.19s look amazing, until you have to buy tires for them.
