changing rims offset question

[mitsumi]

Just curious - What size tires are you using on your new 13" rims?


For those newer to the site, 13" rims don't fit on a 2017+ Mirage due to the larger front brake rotors.

Im using 175 70 13

I have no rubbing issues because i swapped my coil springs before with a Suzuki Swift springs and until now i havent got any problems.

Just comparing my old VX with this TX Monsterims.

The Monsterims looks thinner or thicker and smaller in diameter but I am using the same tire specs 175/70/13.
But maybe because the rims is 13x6 vs the VX that is 13x5 so the tires is a bit stretched if im correct?

I just forgot to weigh in on the new Rims to compare it to the VX I believe VX is 9 pounds per

Honda Civic VX 13” Aluminum Wheel
- 9 lbs per wheel. No Tires.
- 13x5

I am just monitoring the thread wear, since from my VX wheels I haven't got any issues and the tire wear was even from back and front since 2018

Pushing the wheel out would likely have a "poke" stance. I'm personally not a fan of wheels/tires poking out of the wheel well, but to each his own.

Will there be something like a difference of weight distribution to the tires, shocks etc? will there be any concerns when using a negative offset instead of the normal offset?

ANY change to the stock specs will affect the car/parts negatively. The engineers who know maths built the rest of the suspension/steering parts with the stock wheel/tire specs in mind.

Case in point: I've had to replace the ball joint (LCA) sooner than (i believe) most people on here because of the wheels/tires I've been using. But I'd pay that price for both the better look and better performance that I get with my aftermarket wheels and tires.

A possible concern could be shortened front wheel bearing life. The front wheel bearing on the Mirage consists of two ball bearings sandwiched together into a single outer race. In the standard configuration the offset of the wheels places the centerline of the wheels directly in the middle of the two ball bearings so that each ball bearing is carrying half the load on the front wheel. With the negative 6mm offset wheels it places the centerline of the wheel 52mm outwards from the middle of the two ball bearings. In effect the outermost ball bearing is carrying probably all of the load on the wheel and the inside bearing carrying hardly any or possibly even a negative load (upward instead of downward). Actually, it will place the centerline of the wheel about 34mm outside of the wheel bearing assembly, instead of in the middle of it. I'm certainly not saying it won't work, and it will surely look pretty cool, but this doesn't really bode well for the life of the bearings.

175/70r13 tires (22.6" outside diameter) wouldn't be an issue with any 2014-15 Mirage, because it's really no different than a factory 175/55r15 (22.6" outside diameter) tire. The overall wheels are basically the same size. One has more rim and the other has more tire/rubber. Their diameter & width are the same!

175/70r13 tires would be an issue for a 2017+ Mirage, because the 13" rims wouldn't fit over the larger brakes/rotors.
