will this work???

on 8/22/03 i was on my way back to the bay area i had a blow out and one the rim was bent. I can fix the rim but do not like waiting. if i buy another rim i have to wait at least 4-5 weeks.
i was thinking putting 18 all around the car with 18x8 front and 18x10 in the rear would this work. I had 17 and 18 before

Hey Phong - how ya doin, Bud? (not so good obviously - bummer about the wheel!) You need to stop in on your way through P'ton on one of your trips passing through!

You should be fine with the 8 x 18 on the front - that's what I'm running but with 10 x 19 on the rear. You will definitely feel the road more through the lower profile 18" tires though.
What size are your rears? 275/35/18 will give 25.6"; 285/35/18 gives 25.9"
You should go with 225/35/18 tire on 8 x 18 front: That will give a 24.2" rolling diamter. (the 215/40/17 is 23.8", so its about a 1/2" bigger on the height) -
relative rear/front ratio is
stock: 24.7" / 23.6" = 1.05 i.e rear is 5.0% bigger than front
17/18: 25.6"/ 23.8" = 1.075 i.e rear is 7.5% bigger than front
18/18: 25.6"/ 24.2" = 1.058 i.e rear is 5.8% bigger than front

So, actually the 18/18 ratio is closer to stock ratio for TCS purposes than the 17/18, although the tires are bigger overall.

Hey, as far as fixing your wheel - guy who did my old rims did a real good job as you may recall - Jose @ Riteway in Walnut Creek- Phone # 925-933-4046

There are several problems with bigger rims. One of them is that they result in shorter sidewalls. Those shorter sidewalls on an 18" front rim will make your wheels more susceptible to bent rims from hitting potholes and ruts. Other disadvantages are greater weight, less availability of suitable tire sizes, more expensive tires, front tire sizes that rub, etc. I would recommend sticking with no more than 17" in front. That will also let you fix the rim, which will cost a lot less than buying two new ones.

thanks for the info friends.I will try to have my rim fix and the same time i think i will buy another set diff style for spare that way i can drive the car everyday

hi ken, good to hear from you ,i call you on the day i got the blow out coundn't reach you so i call brent. he brought me the spare i end up not using his because my brother brought me my stock one.but it was very nice off him to came to the rescue.

Currently i am trying to fix up my bachelor pad so i can have some nice looking chic to come and party.Hopefully we'll meet agian soon and have some coffee.

Thanks very much to you brent ,for coming to the rescue.

You should go with 225/35/18 tire on 8 x 18 front: That will give a 24.2" rolling diamter. (the 215/40/17 is 23.8", so its about a 1/2" bigger on the height) -
relative rear/front ratio is
stock: 24.7" / 23.6" = 1.05 i.e rear is 5.0% bigger than front
17/18: 25.6"/ 23.8" = 1.075 i.e rear is 7.5% bigger than front
18/18: 25.6"/ 24.2" = 1.058 i.e rear is 5.8% bigger than front

so the bigger the number, the smaller the tire is? some explain to me about the number of this thing 215 bigger than 225? 35 bigger than 40? someone put me straght..

You have to be careful when saying "bigger" - I was only citing the rolling diameter.
The 3 numbers all work together to give the actual diameter of the tire
e.g. 225/35/18 means
225 - this is the width of the tire in mm
35 - this number is the % of width of the tire which = the sidewall height i.e in this case 225mm x 35% = 78.75mm
18 - this is the diameter of the wheel (in inches) that the tire fits on. (1 inch = 25.4mm)
(It's a little strange that metric & inch measurements are mixed together!)
To get the final rolling diameter of the tire, convert 18" to metric then add 2 x the sidewall height
in this case (1 8X 25.4) + (2 x 78.75) = 614.7mm or (614.7/25.4)" = 24.2"
225 is wider than 215; 40 series is a bigger ratio of height to width than 35; 18" diameter is bigger than 17";
But depending on how the combination of sizes of the 3 numbers work, the tire may or not be bigger!
