I am considering swapping the all season tires from a 2004 S to a 2003 SR for the wintertime.Not sure if this will work, has anyone ever tried this?
Thanks,
Bob

 

By SR do you mean STR (S Type R)?

What size wheels and what details (incl load rating etc) tires?
My first reaction is: no. (And why?)

 

I think it will if the take off wheels are 18", but don't take my word for it...

You will need to test fit the wheels since brake clearance will be an issue when fitting standard S wheels to an STR...

Oh, and living in Northeast Ohio, I do understand why you would want to... Narrower all seasons would make it drive better through deep snow.. Just be careful how it handles on the dry. Nothing worse than having to do a sudden lane change and she doesn't perform like you're used to...

 

You may want to check out the offsets as well. To the best of my knowledge STRs run staggered wheels,ie, the rear wheels and tires are larger than the front. As Jeff mentioned earlier, STRs have 18" wheels while most regular S-Types have either 16" or 17" wheels depending on year. You may want to consider getting an extra set of rear rims with winter tires mounted.

Over here, unless you use appropriate wheels (rims) and tires you'd invalidate your insurance.

My 2004 STR has front 245/40 18x8 (minimum load rating 93), rear 275/35 18x9.5 (minimum load rating 95) and I understand the offsets are all 60. (I actually have 99 load & Y speed rating.)

I think the Handbook has a table showing what's permitted, including for winter tires.

 

Theoretically, it should work if swapping just the rubber. If the all-seasons are at least 245 wide with a wheel size of 18, then they can be stretched to fit on a 275. I also wouldn't go any bigger than a 50 profile, since the STR's have 35's and 40's as the OEM spec. As for mounting, use the STR rims. It will save you many headaches due to the brakes and calipers being so large. Like Mike mentioned above, do not use the 3.0's or 4.2's wheels as the front and back rims on a STR are different sizes (staggered), with the rear 1.5" wider than the front.

As for getting snow tires, it is the best thing you can do to your car for winter use. I purchased a set of Yokohama W-Drives (dedicated snow tire) last year. Man, are those things phenomenal in the snow! I ended up doing 245/40 all around and have had zero issues with that setup.

 

The wife has a 2004 S 4.2 w/ 17" tires but she does not drive it in the winter.
My son purchased a 2003 STR with summer 18" tires. I was thinking of swapping the tires, car to car, for the winter since the 2004 S sits in the garage on snowy days. Just wondering if the S wheel will fit the STR for the winter. I know the 17" tires will be about 0.7" bigger in diameter but if they fit and get thru the snow who cares? Just want ot make sure that they will fit the same hub and not interfere with the STR brakes.
Thanks,

Probably covered in the previous replies (see Handbook, for example).

 

I don't think the 17" will fit. I think the brakes on the R force you to go to 18" at least. The best way to find out is to test fit the wheels and inspect for clearance. You won't have suspension rub issues at only .7 of an inch difference in diameter as well as the offsets used by the two models are very close.. (heck 2008 S Types came with the front R wheels all the way around).

Now, if they fit, make sure your son test drives the car very carefully in an open lot somewhere. Remember that the suspension on the R is set up for larger wheels with a staggered fitment. This may have a very drastic effect on handling.

On previous cars I would run up size wheels and tires in the summer and switch to the standards in winter. Since the car was originally built with the standard 16" wheels it was no big deal. Just did a 4 wheel alignment after each swap (That is very important as well since alignments are done with the tires mounted!). Now, a previous girl friend had a sport suspension Jetta with factory 17" wheels. When we got a winter set from "the rack" mounted on 15" wheels that car was an absolute bear during quick lane changes and ramps even after an alignment. It was just the fact that the suspension was tuned for the 17's and really wasn't set up to handle high profile tires. Then again... It was as unstoppable in the snow as my Cherokee with the blizzak's fitted so it was a trade off she was willing to accept.

All that said... If they fit.. be sure it is a trade off that your son is safe with.

I see now what you mean. Fitting the same hub isn't the problem so much as enough clearance for the brakes. Unfortunately, I don't think the 17" will fit on the STR. This could work with the rear, maybe. I believe there is a 3/8" gap between the rear brake caliper and the rim. However, there isn't even a 1/4" between the front caliper and the rim. It is a very tight fit, and that is where you are likely to run into problems.

While snow tires/all seasons make a light and day difference in wintery conditions, it is possible to make due with the summer tires already equipped. I bought my car in late January, which is the dead of winter where I live. Of the 4 times where it really snowed, there was only once where I could not drive with the summer tires. Once the roads are cleared, there aren't really any issues (aside from being aware that the summer tires handle differently in the winter due to temperature).

But this is an absolute last resort if you are unable to acquire the snow tires/all seasons recommended or the 17" doesn't fit (which is likely the case).

 

Hi
I'm thinking about buying some new tires for my dodge charger, and the orginal factory tires are grand touring tires. I went to tirerack and realized they also have high performance all season tires i could buy instead of the grand touring. My question is whats the difference between the two tires?I'm a performance guy myself, so instantly was leaning towards buying the high performance all season tires, but i don't know if it will benefit me more then the orginal grand touring tires.

 

I'm looking for tires for my 2005 Jaguar S Type. 3.0 6 cyl. It barely rains where I live and the roads a bit rough in spots. 100 miles per week on the highway driving and around 50 in town. I don't do anything crazy or anything when driving. I'll certainly drive fast on the highway. But no sharp turns and / or etc. Looking for as smooth and quiet ride as possible. And a tire that can handle less than smooth road conditions.

 

Maybe is an off-topic question but I want the exact tire and wheel size of the Honda Civic 2000, I have this car and I want to upgrade their but I don't know the wheel size and it's not mentioned in the wheel so please help me out.
