15 vs 16" rims now with offset issues :( FML

[MR 325]

going from a 195 65 14 to a 205 50 15 loses about 3 mm overall diameter

I don't even know why you posted this BUT 205/50/15 is an undersized tire. The difference is NOT 3mm, it's almost 1 inch. The correct sizes for a 15" wheel would be 205/55 or 225/50.

LOL wtf? thanks? haha im not sure what for though

[GAbOS]

but im not sure if i want to drop to a Rota for another 15" or stay at 16.

Fixed ;>

Not true. The overall diameter of my 16" RGPs with 205/50s on them is smaller than the overall diameter of my stock 14" weaves with (stock) 185/65s.

if your car sat on wheels then yes, it'd sit 1/2" lower.
but in reality, your car sits on tires and the tire sidewall dimensions dictate your ride height, not your wheels.

im confident i can get my tyre and wheel set up to work looking at your set ups.

those look great! What size wheel and tire combo are you running? i just picked up a set of 16x7 et18 and 16x8 et15 and am trying to figure out a good tire fitment. I realy dig the look of yours.

BBS RS001 15x7 et25 with 2.5 lips front and 3'' lips back. Final specs: 15x8.5 et06 and 15x9 et00 with 195/50-15 all round.

BBS RS174 16x7 et33 and RS244 16x8 et33 redrilled to 4x100 with 3'' lips front and 3.5'' lips rear. Final specs: 16x9 et08 and 16x10 et08. Tires are 205/45-16 front and 225/40-16 rear.

so i just had a quick measure. with my m20 POS bottom end sitting in the boot the back sits about where i want to lower it to using my GC coilovers.

and according to the trusty ruler i have 25mm till i get to the rear gaurd, from the tyre. not the rim. and tyre comes just past the edge of the rim.

so currently i am running 7" et20 and with 8" et10 i should poke another 23mm

and according to the trusty ruler i should JUST sneak 225s under my gaurds with rolling and maybe a slight flare.

what are your thoughts on this? think its doable?

thanks, leigh

[e30leigh]

SSHHIITTTT!!! so i just got back from the tyre shop.

the rota grid-v's hit on the calliper. even the et20's i want a 225/45 tyre
hence the issue.

i can make them fit with a 10mm spacer. but i dont think then that i can get the 225 under the gaurd.

what sizes are people running on 8's with et10? can a 225 fit under there?

For comparaison

15''



16''

These may not be called a te37v but, they are a grid-v. They are a straight up replica.

[e30leigh]

the amount is minimal though surely?

16 = more clearance for your pan

Not true. The overall diameter of my 16" RGPs with 205/50s on them is smaller than the overall diameter of my stock 14" weaves with (stock) 185/65s.

[e30leigh]

yea i think 225/45/16 works out to be the same over all diameter as stock wheels and tyres anyway

[bimmerteck]

if you run the correct size tires it doesn't matter what size rim you're using. It should come out to the same overall diameter.

qft.
