I was thinking about upgrading to 19s and want to keep the same rolling diamter. I have used michelin and dunlop tires in the past and they are "low profile" but I have definetly seen some much lower profile tires where the side walls are much thinner so-to-speak.

Who makes these tires?

 

For 19 inchers see OEM measures.

Front max: 8,5x19 ET12

Rear max: 9,5x19 ET28

Tyres 245 F and 285 R max.


Good luck.

 

rear in the 19 is 275. You can always use a lower profile tire, but one one combo of sizes will keep you at the correct rolling radius. i for one would like to see a move back to slightly taller sidewall tires...some of the 30 series stuff is getting to be too thin.

 

I'm no expert on this, but here's my 2 cents:
The people who you've seen with much lower profile tires (side walls are much thinner) on 19s, did not care about keeping the same rolling diameter. If you want to preserve that, you will need to go with the tire size recommended on the previous post.
If you want to have much lower profile tires (where the side walls are much thinner) and keep the same diameter, you could go with a larger wheel, say 20, 21 and a much thinner side wall tire size.
Good luck

 

You have missed a long discussion on this Forum.

18 and 19 R max 285's!

The radius is within measures and looks a bit plus.

 

If you'd like to keep the same rolling diameter for your 19" tires, I would suggest the following sizes:

Same all around: 245/35/19

Staggered:
245/35/19 fronts
285/30/19 rears

You can get an even lower profile if you move up to 20" tires/wheels.

Same all around: 245/30/20

Staggered:
245/30/20 fronts
285/25/20 rears

As far as tire brands are concerned, I did a simple search on tirerack.com and you should be able to find a several manufacturers that make the combo sizing.

Michelin and Dunlop do the same 'low profile' tyres as other manufacturers... There's no special make...

As already stated the OEM 19" are 245/35/19 on 8.5J front and 275/30/19 on 9.5J rear - best to stick to those sizes unless you're a bit adventurous...?

 

Almost every tire manufacturer makes low profile. For the best results, you need to find the size where if you change to a different rim diameter 17" to 18" or whatever, the overall diameter including the tire stays close to the same. Here is a link to a calculator that will help...you might find a better one too.

Also by looking at members signatures, will also help determine the best sizes as most of us have been through this already. Good luck and post before and after pics!

 

So will getting 19s with the 245/35/18 on all 4 tires proide the same rolling rate as my current 245/40/18s?

 

245/35/19 should put you pretty close to your current 245/40/18 tires.
