hi, somebody pm'd me and asked why the 22's not the 20 inch wheels so here were the things to consider:
stock: 235/60 R18 vs aftermarket: 265/45 R20
tire rotation difference: 0.960% almost 1%
speedo: 100kmhr vs 99km/hr actual
more vibration, thicker tires, heavier
(I tried dealerships offer before on 20"s)
stock: 235/60 R18 vs. 265/35 R22
tire rotation difference: .69% (.7%)
speedo: 100km/hr vs 99.3km/hr actual
less vibration; it seems..
(it doesn't feel slower, it actually spins a little during acceleration)
24"-ridiculous..-rubberband tires, likely damages rims fast
And to help decrease leaning and rough ride, i bought urethane cushions installed into the middle of the spring: benfits below (from korea) birthplace of kia
1.Comfortable Driving when passing overspeed preventing block and bumpy road
2.Prevents leaning with coil spring tension control when making a sharp curve.
3.With cushion improvement, it reduces fatigue when driving long distance.
4.Protects shock absorber from the shocks(Durability extends more than 2 times)
5.With car height restoration, it provides stabilized driving.
this helps esp. for owners of sx that has stiffer ride (as others say so)
