I was told that I could fit a 245/40/18 or 19 in the wells with the IPD lowering springs I would like to know what the fitment is for the 850 wagon..... any help would be nice......

 

Depends on what car you have. If you are talking about factory size you can check the manual, most are 195-60/15.

sorry I am wanting to know what larger sizes will fit with out rubbing..... I want to get a set of IPD rims in 18 or 19 I was told that I could fit a 245/40/18 or 19 how many of you are running tires larger than a 225 in a 18 or 19.....???????

 

@$#%&

 

As you may know, the R's come with 17's. The proper tire size for them are 205/45-17. I hated them on my yellow sedan but went to 215/45-17's on my wagon and they are not to bad.

My main complaint with the wheels & tires on my sedan was that I had a flat almost every month. Then tires were getting damaged every few months and it looked like I would never wear out a tire on that car. Then I lost a few tires due to rubbing, etc.. So I went from having tires last 80,000 to 90,000 miles to less than 20,000.

Then the car did ride hard. Being a person that has driven comfortable Volvo's for almost 700,000 miles, this was tough. I do realize that the T-5R has tight suspension which was a contributor, but the tire situation just frustrated me a lot.

The wagon rides a little tight and has about 200,000 miles on it (the sedan only has 113,000 on it when I sold it). I really could not imagine trying to put 18's on an 850. I had some rubbing problems with the sedan but not with the wagon.

Have fun and I hope you have deep pockets. When I see people rolling with low profile tires, I call them a big baller. They have to be to afford to keep rubber under their car with all the damage they get with bubbles and bent rims.

 

When I first got my car some one had put 215/50r17 on the front and they rubbed! I moved them to the back and on big bumps when turning they would rub in the rear! So I'm running 215/45R17 no rub! Not much of a difference but it is!

 

It would look sweet but rub like crazy. I put 225 slicks on mine and it was right at the strut tower and knocking on the fenders. I doubt you could go any wider in the front. Whatever you do in the 18" or even the 17" beyond the recommended tire size you can expect a rub now and then. Full lock is the worse. I rub now and then at full lock with 215 45 17 and H&R springs.
The rears are the same size with 15mm spacers and rub when I have 7 people in the car on bumps. The nice part about the rear is I can say you can go wider because there is that 15mm spacer I have back there that could be additional tire with the right size rim.

 

thanks for the info thought about it for car show but dont really know right now just thinking that the info is helpful in making a decision.... really just want some 17s.....

From what I was looking at whoever it was that said a 245-40-18 would fit must not drive the car. It might look pretty mean sitting someplace at a car show but it's doesn't look like there would be any room for it to turn and any bump would put the body down on it.
It looks like the critical diameter seems to be just under 25.5 inches so as not to rub when it leans or on bumps.
The tire width seems to be able to handle up to 8.46 width as long as it's the smaller diameter. If you go over 8.46 width as in the 245's it would need to be smaller than the 24.6 diameter and even then it might not fit.
The speedometer calculation is just a guide as I ran all the tires against the 205-45 that someone said was a stock size.

Anyone running any other sizes that fit or rub a little?
I have stock 16's and I'm thinking of keeping them and going to a 215-55-16. Any one running on a set of these

 

I don't know how a larger tire would make the speedo run faster. I always thought that a smaller tire would turn more often and make the speedo go higher. I'm good at math but bad at physics. Go figure.

 

At speedometer 65 the one rated at 65 would be doing 65. The others would read speedometer XX doing 65. You are correct, the smaller tires spin faster.
It's just a guide as to how far off your speedometer would be.

 

will any of the rims from like the s60r or anything like that fit or is the off set to far off???

 

Yeah, Pegs will fit, but they are so played. If you're running Columbas, then the wheel is 16x6.5 et36 or 38. Can't remember. Go to willtheyfit.com and enter in all of the specs for your wheel. Look at your inset and your offset of the wheel you currently have, and then plug in the in new wheel and compare specs. That will tell you if the wheel you want to use will fit or not.

 

thanks I was just looking on craigslist and found some wheels I like kinda like the ones in your sig.. that is why I was asking dont want to drop 500 or 600 on wheels that I dont know for sure will fit.

 

For example, my Tethys were 17x7.5 et49, plugged them into that site and I got an inset of 144, which his what I want for inner strut clearance of the wheel. Measuring from the edge of the wheel to my outer fender, I realized that the max poke I wanted was 72mm. This allows me to plug in any wheel into it, see what size adapter/spacer I would need to get inner clearance 144mm, and then see if the wheel would poke or not and how much. Very helpful site. Then if you take it a step further, you can measure from your hub to the outer fenders, use this site:

Wheel Offset Calculator - The Ultimate Stance Calculator | Jonathan Rowny

and plug in your wheel/tire specs, it will show you where in relation to the fender your wheels will fit.

These are the current calculations I just did a couple days ago comparing my Tethys to the set of BBS RS' that I'm putting on the car. The second site I linked you has a spot for adapters/spacers so you don't have to fiddle with the offset to take into account those measurements. Really helpful sites if you want to figure out what wheels will and will not fit.

 

thanks again...

 

With the tires it came with 215/50R17 did it have lowered springs or stock?
