staggered look?
that will make the speedo off. Just stick to as close as possible to the original
overall diameter of the original wheel/tires and you'll be ok
Naturally there is the issue of not being able to rotate the tires, but oh well. My car is an extreme case since I am running BFG KD tires all the way around. They are not only directional but also positional, meaning there is a left and right tire. So in my case, each tire only has one place it can be.
As mentioned by cocimitch, it's no biggie if you wanna do a 18/19 combo, you just have to keep the overall diameter of the tire as close to 25.6" as possible and you'll be fine. To do that, you just have to pick the right tire. You will compensate the larger diameter of the wheels with tires that have a lower aspect ratio, meaning, a tire with a smaller, and stiffer, sidewall. That improves handling, but isn't the greatest for traction.
Go to Disount Tire or Tire Racks website and take a look at the dimensions of each tire that you are interested in and pick the one closest to 25.6" and you'll be fine.
Good luck!
). I can't think of an exact measurement off the top of my head, but let's pretend. It'd work like this, 255/60/15 would be 27.0472" high very close to the same as a 295/55/19 (27.1299). Do a search, I'm sure you'll find it. All the tire reading is: 295 (tread width in mm), 55 means 55% of 295mm, and 19 is the rim size, ie - 295/55/19. So all you do to find the tire height is 295 - 55% (which is 132.75mm) then multiply that by 2 (since the tire is a circle, you'll be measuring the sidewall twice) which would give us 265.5 mm, convert 265.5 mm into inches (9.7441) by finally add in the size of the rim (19). So we get 27.1299.
Easy as pie.
