I have an '87 230S i want to replace my tires and rims what size does everybody use on there quadsport. I think 21x7x10 for the front and 22x11x9 for the back is stock but i dont know the numbers for the rims

 

if i were you id go for 20x10x9's in the back. theyre common and will improve handling ALOT.

for wheels, just get douglas black or red lablel's from motosport (blues arent reccomended). have them search by machine make and model, and they will provide you with ones with nice big offsets. you should gain about 3" in the rear just from that. look for a 9x8 rim for the rear, and a 10x5 in the front.

tires are all about preference. i personally run stock yfz450 tires in the rear (dunlop kt355) and i LOVE them. theyre 4 ply so theyre light but still tough. sliding is extremley predictable and they EXCEL in everything from hardpacked to mud. they seem to wear nice and slow, and provide great ride quality since theyre radial.

for the fronts, i just use cheapo cheng shins and my opinion about those is the same as the rears.

let me know what tires youre looking at and ill see if i can help you out with them.

good luck!

 

should i stay with the 21x7x10's for the front if im gonna put the 20x10x9's on the back?

 

yeah definatley. 21x7x10's are super common and work great for any use (MX, XC, etc).

let me know how things work out.
