Thanks, stupid Mexican tire shops ill- informing me :sly:

Thank you cj.surr , I will probably go with those 205/60's i can just modify it later when i have more dollar signs =P

@drivinfaster - I know those 16" are good for show but i just got these retro 15" and painted them so i wont be parting with them but in the future i see 17"s thanks for the advise though!

Cross spokes? You mean from a Z?

Indeed i think they are but just older ones =)

hey guys i am just inquiring ,
I seem to take of slower and hit a slightly higher rev when i accelerate
if i match up 205/60's on the front with 215/60's on the back
will this equalize this and bring me revs down a bit and shift up smoother?
i have a auto but i have been told my set up is tricking my engine into thinking its going up hill.

lol wut.


reason i lost that race: i got the wrong tire size.... it thinks its always going up a hill.

Back in my day... we had to drive uphill, BOTH ways. In the SNOW. We couldn't afford to put smaller tires on the front!

Lmao CJ!

Phen, make a mental note to ignore anything that person tells you about cars ever again in the future.

lol i know i sound stupid but im just asking you guys as i havent the experience with bimmers. but thank you.

the setup i have 195/ 60 and 215/ 60 so its a fair gap thats why i wonders if i need to sqaure it down a bit as in making them closer sizes =P

Btw i will ignore them haha that what i got you guys for huh lol

The important thing is that the overall diameter is identical side to side. Front to back won't hurt it, even on more sensitive models like the E39 that monitors wheel speed deltas much more intensely.

You're a tad under and inch less diameter up front. I wouldn't worry much about it now, but you should get the same when you replace them.

thanks heaps for that i will note that when i go to replace them later down the track,
thanks put my mind at ease =)

im thinking changing to larger tires up front has anyone got an idea of wether 215/60 R15" will fit on the front set of my e36 318i ? will this fitt with space to steer safely?



Or should i go smaller at the back?

I do like the beefy bulge at the back but not ertain.

You usually get the best (most predictable) handling with the same size tires front and rear.

What size do you currently have and what is your wheel width?

I currently have 215/60 R15" at the back
195/60 R15" at the front


I feel like it takes a longer to gain speed than it did orginally with even sets but will having
215/60 R15" all round effect the speed or will it help

Me myself was wondering how a set of 18s would do on a set of Toyo rubber bands

Depends!

What is this thread even about? I'm so confused right now.


And e30s can still rock the 15s, just for the record. Yes, that comment was the only thing I understood in all of this.

The ones on your E30 are 16" aren't they, Amber?

And, oh hey!

You know, I'm not actually sure. Next to Ash, they all look tiny. I think they may be 15s, I'll check tomorrow.

It does take longer to get to the speed your speedometer indicates. Stock sizes are 205/60 x 15 or 225/50 x 16. Your 215/60 tires are larger diameter than stock which means your speedometer is reading slower than you are actually going. That plus the larger diameter effectively decreasing your gear ratio WILL make you slower.

That makes sense thank you what size tires would you recommend for a good performance and gear ratio ?

Go here:

http://www.miata.net/garage/tirecalc.html

Enter your original tire size in the left side (205/60/15) and then enter the wheel size you want to use. Change the tire cross section and aspect ratio until the error in the line below the diagram is minimized. Example:

205 60 15 compared to your suggested size of 215 60 15 results in an oversize mismatch of almost 2% too large in diameter. That may or may not be acceptable to you.

I have 235 40 17 tires on one of my E36s. They are 1.1% too small compared to stock, which I find acceptable. The other E36 has 205 55 16s, an error of less than 1%.

oh thanks man i have used this calculator before its very helpful !

the originals on there were 195/60 r15" but i think ill go with 205's now just for good measure =] thanks for that.

also is it better to have larger rims and smaller tires or the opposite?
