Help With Rubbing!

so im new to rims/tires and i need some major help! i just bought some 19" csl reps and im having problems with rubbing on my SHOCKS.

they are 19x8.5 in front and 19x9.5 back. currently they have 245/45 and 275/35 tires. now i know the front tires are way too big for my e90 325 but my question is, if i use a spacer (maybe 5 or 10mm) will that help with the clearance? also what is the best tire size to use? im not looking for complete aggressive like this previous owner had.

please help me!! i want to keep these rims cause they look so nice!

What are the offsets?

I would probably use 235/35/19 front and 265/30/19 rear.

unfortunately, the guy i bought them from does not know the offsets. i just know he had them on a e46 m3. the back with 275/35 actually fit fine. it was just the front that rubbed so bad. im in the works of looking for 235/35 and maybe using a 5mm spacer to just push it out from the shock area. but im not sure exactly what to do

You can measure the offset yourself or it might be printed to backside of the wheel.

http://forum.jdmstyletuning.com/show...T-on-your-Rims

Still 275/35 is wrong height ratio to 19 inch wheel correct is 30. 275/35 is for 18 inch.
Also if you use 235/35/19 and 275/35/19 your difference in diameter is 1.1inch/4.1%

You might not need the spacer if you down size the tyres.

exactly what monacoblue said. Its not the offset nor spacers that will help you, Its that dam 45 series which is hitting your strut perch.

thank you so much for that tutorial! i will do that asap to figure out offsets. so the 275/35 is wrong but is it okay for now? if its not rubbing or anything? i need to fix this front rubbing so i can see if i can keep the rims or if i need to sell them

235.35 has your name written on it lol, yet its a closer match with the 275.35 rear. In the future the rear should be a 265-275.30. 275.35 will throw your speedo off.

Careful with used tires, as most of the time the dismounter/owner will have the "i dont give a fuck attitude" about them. Make sure the tire bead/mounting surface dont have any major gouges, inspect for plugs/patches/bubbles/internal belt separation or else youll be on the side of the road.

while i do see your concern, i was MORE concerned with the tires fitting properly. but now seeing from your comment and researching a lot of 19" rims, 235/35 seems to be the reasonable size. so now im thinking of spending the extra bucks to get newer tires and eventually replace those 275's.

265/30 is what the standard on here is with the 235/35 front's, however a 275/30 or 255/30 are also fine.
