Rishie's FITMENT RECIPE

could i run a 16x7.5 wheel with 65mm offset and 225-50 or 215-55 without rubbing or sticking out form under the fenders?

OUch...65mm offset? I think that'll take you waaaaaay the other way and have ur tires/wheels rubbing against the fender liners, and effectively enlarging your turning cirlce...

Most people I've met who are using 7.5"-wide rims on a P5, make do with a 48mm offset.

Remember, rear fenders/track can be a bit wider on a sedan than a P5, which means you have a few more mm's to play with...or rather a few less...

It is my understanding that 42mm fits better on a sedan than on a P5...go figure...

About the same Q. I am looking at some FD wheels for auto-xing. 16x8 not sure of the offeset right now, maybe 50 or 55. From what Dave mac has said I need coilovers and some camber to fit 245's what about 235's?
 
hi guys, im from the uk, are our cars both the same regarding wheel fitments etc. i have a 323 sport, which is basicly a protege5.

i've read the entire thing, and it was really helpfull, i have ebachs all round, and i want some 18s on, from reading it im thinking i have to get some wheels that have an offset of 48, would this fit without rolling the arches, and does it look good? or would an offset 50 look better?. i'll be running 215/35/r18 tyres on them.

does anyone have any pics of protege5s running with 18s? and lowered .


thanks for your help guys.
 
I have 215/35/18" on 18x7.5's with 50mm offset with full coilovers which actually give you less clearance due to the adjustmant collars. I have about .200" clearance to the collars and .200" to the fenders in the rear with about 1/2degree of camber. I am dropped about 2.5-3".

thats a sick ride mate, so u dont get any rubbing over bumps etc? i know what u mean about the coilovers had the same problem on a peugeot 206.
 
No rubbing in the rear at all. I actually had it about 1/2" lower but when entering slightly inclined driveways and such the fronts would barely rub. I had to roll into them at like 1/2mph and it became a pain in the ass trying to get out of the way of traffic coming up behind me. And dangerous!!
 
Thats great stuff mate, im going to be upgrading to coilovers soon anyway. thanks alot for you help. Where abouts to all u guys get your wheels then? cos et 50 is pretty rare over here in the uk.

cheers
 
I bought mine thru a friend for wholesale cost and they were 45mm offset. But I am an engineer/mold designer and have a machine shop at my disposal. Just faced off the backside 5mm after indicating it in.

would that affect the structural integrity at all? I have a set of 17x7 +40 that I'd like to get machined to +45 so they don't rub.
 
You need to make sure that the wheel is MAX 7.5" wide and with an offset between 48mm and 52mm.

Keep in mind that you don't want to machine too much off the backside of the wheel because it will make the "lug seat" thinner. Stick within a 3-5mm tolerance at most and you should be ok.

Thanks, Rishie
 
I have around 40k on those wheels on my second set of tires and the wear is normal and even plus I am pretty much slammed and no problems what so ever with my tight stiff ride and horrible freeways by where I live. 5mm is about .197" just make sure if you do it that you have enough material left there. I also did the same on my old 17's.
 
I reckon nibbling 10mm offs a bit extreme, these wheels i got only cost me 50 pound and they kurbed and nakered anyway. might purchase a set of 45 offset wheels im watching on ebay, and get 3mm nibbled off. i think thats safer.
 
guys can anyone answer my problem?

based on my research and taste, i ordered my first new set of rims ever at 17'x7.5, so the guy says ur stock is 195/50/16 dont go over 205 for tires, and 17 for rims, it will rub, and i dont have lowerings.. i took his word and proceeded with the order and paid everything in full. Now i see the january monthly submissions thread and noticed everybody had 18s im wondering if i could have bought 18s instead

so i checked the first page of this thread, there i see i need at least +48 clearance, but im afraid to risk 18s on non lowered p5, what do u think of this whole story could i have bought 18s with 215 tires instead? or could i have bought 18's with 205 but still encountered rubbing problems?
 
how about rims, im more worried about that, could i have gone 18s with 205?? any rubbing??

205s are really narrow for 18s, since most 18s you'll fit on a Protege are 18x8 I think. You'd want 215/35/18, which is a little rubber band of a tire, really harsh ride, etc. At least with 17s you can do 215/40-17 which gives you a little bit more tire on there.
 
oh thanks for the reply, considering 17s on 205, is there room for a max. 2" drop? im still looking at springs some describe it as 1.4, 1.6 etc.. hows zenn springs btw?
 
Ok so basically it comes down to this:

Tire diameter. You want to keep the same tire diameter, so your gearing and speedo don't change, while being able to get as wide a tire as possible.

If you look up the stock P5 size in a tire calculator you will find 195/50/16 and 215/35/18 aren't very far apart.

195/50/16 = 23.68"
215/35/18 = 23.93"

205/40/17 = 23.46", a little shorter than stock. I want taller, not shorter.
215/40/17 = 23.77", a little taller BUT REAL REAL NICE. hehe.

Therefore you know from a pure "gearing" aspect you're good to go. Now the issue comes down to the ADDED WIDTH of the tire. In order to ACHEIVE MAXIMUM RUBBER, you will need to compensate for this by pushing the wheel farther into the wheel well. Fortunately the Protege 3G's have enough "backspacing" to accomodate for this.

So in the END it all comes down to these TWO QUESTIONS:

1. How wide is your wheel?
2. What is the offset of that wheel?

If the answers to those two questions fall into my "RECIPE" then it should spit out the tire size you can run.

If you bought 17x7.5 +48 offset or higher wheels then you can run a 215/40/17. If you didn't then you can't.

I like this tire calculator, most guys use the Miata one.

Ok hope that helped a little.
