Hi,

I own a 2003 G35 Sedan, I have 36K miles on it and it still runs great. Last weekend when i had a problem with my fuel assembly, I took it to the dealership and they suggested that i should get a new set of tires. They quoted me close to $1000/- . I had got the tyres checked at SAMS club and they quoted me $520/-(Including Taxes). The tires were michelin 215/55/R17. I was wondering, if i should be getting the same tires or Can i get some thing like 225 or 235 from somewhere else. Suggestions are welcome. I am open. I would like to get one set of tires which would work in winter and summer.

Thanks
Praveen

 

The next size up that is popular is 235/50-17. There is a number of more tires in this size then the standard 215.
Might want to check your sams or goto tireack.com for other tires.

Alot of people have been buying the Avon tech tires. They seem to be getting some good reviews from what I can read, plus they are pretty inexpensive.

Hope this helps.

mike.

 

I replaced my 215/55/17s with 235/50/17. Less than 2% speedo error with this size. First replacement tires were the KUMHO ECSTA KH 11s. The rears wore out really quick, overinflated I guess. I replaced those two with the Pirelli P zeros. The Kumho's were a tad above $110 apiece and are a low price alternative. The Pirellis were around $250 apiece and ride GREAT! You can tell a big difference between the cheap vs expensive tires. I will be replacing the Kumhos with another pair of Pirellis. This car does not deserve cheap tires.

 

Mike,

I see you put the coupe mid-pipe on instead of a new exhaust! How do you like it? I wanted to do the same, but heard too many bad stories of droning with the HKS muffler attached to it.

 

Thanks Mike, I will shop around and will look at tirerack.com too. If i use the 235 tires, is there a considerable difference on the car. Does it have low clearence, how does it affect the millage of the care and how does it affect the performance of the car and the how is the performance of these tires.

Thanks

 

Can i Put 235/55/17 on the Car. Please, i am very naive.

 

You could, but don't. They'll be too tall. Stick to 235/50-17 for the best overall fit with the widest tire you'll want to put on the stock rims.

 

I have also found on a website that i could use 225/55-17 or 245/50-17, If so which one would be better. I need to understand what the first number stands for.

Thanks

 

The first number is tread width in millimeters (mm), the second number is wall height expressed as a percentage of width (aspect ratio).
So a 225/55 tire would be 8.86" tread width by .55 x (8.86") = 4.87" wall height

All tires have a specified range of rim widths and a recommended rim width. Going towards the limits of the range will affect tire performance and wear.

 

I have the 2005 sedan MT6 with the ST supension. It has the 18" rims, what is there width? What is the widest tire I could put on it and still keep the speedo with in a couple of MPH?

 

I believe the 2005 6MT has 18"x8" rims.
The speedo is affected by the circumference (or rolling diameter) of the tire which is a combination of the size and wall height.
You have to look at both to determine how much your speedo is affected.

 

Yes, I understand that. Now what size tire? 235-50's or what?

 

I have 245/50-17s. They work great but they are just a little too wide for the stock 17" rims, as well as being a tad short. I'd stick with 235/50-17.

...On the stock 17" rims. If you really have 18" rims, I can't help you as I don't know what tires are supposed to be on those.

 

As I don't have access to the numerous tire manufacturer's data without expending some effort, my suggestion is for you to first determine the following:

1. What ride quality do you want -- hard, soft
2. What performance do you want -- wet handling, dry handling

Then you need to determine:
1. What is the OEM tire sizing and calculate the rolling diameter.
2. Which tire (manufacturer) best suits the above handling criteria
3. Choose a tire sizing based on the maintaining the tire's diameter to within your acceptable speedo error.
4. Check the limits and recommended rim width for that tire.

For anyone to boldly say you need to go with 245/45... may not suit your preferences.

 

Yes, Avon tires are for me as they have great reviews. I'll try them for sure at $110. per.
