2013 cx-5 gt
Hi guys ,new here
Wanna get wheel spacers for my 2013 CX5 gt ,but don't know if that's a good idea ,
Due to safety issues ,
So looking into getting wider tires and wheels ,
Don't know where to look on how wide I can go
wanna go at least another inch wider ,
Can anyone help me out on the number on the tires
Thanks
 
Also is possible to go slightly wider on tires and keep the original stock 19 inch rims or vice versa .?
 
7 inch wheel to 8 inch wheel should be fine with the stock tires. You are just loosing a little bit of wheel/rim protection from the tire, but you still have a little bit of cusion.
 
19x7.5 with 235/55-19; 19x8 with 235/55-19 or 255/50-19 is possible with them being minimally larger diameter than stock.

Also mind your offsets - anything in the 40-48mm is okay and will make it more flush with fenders.
 
Here are the specs on the stock 19" wheels, which is identical to the 17" wheels in everything except diameter.

19" x 7.0 "
offset = 50mm
bolt pattern = 5 x 114.3mm (5 x 4.5 is equivalent)
hub bore = 67.1 mm
 
I wouldn't worry about adding an inch of contact patch to your tires. You will likely experience diminished fuel efficiency.

Instead, settle on a 235 series tire, on a 7.5" wheel with an offset of perhaps +35 to +40 et. This will give you a flush look, with only slightly meatier tires.
 
I was surprised what a difference it made in the appearance/stance by going to just a 45mm offset from stock 50. 5mm change seems like it should be imperceptible but after seeing it I would not want to go much less.

The tires on the GT are Toyo A23, sized 225/55-R19, selling at tirerack.com for $265 each as a "Grand Touring All Season.

You can go to one of two "plus-zero'" sizes on your 7"rims, according to tirerack: 235/50-R19 or 245/50-R19. You might be able to go even wider to 255/50-R19, but you may start to run into rubbing issues.

The second plus-zero option has a nice sweet spot option: the Pirelli P-Zero Nero All Season, sized 245-50-R19, is only $179 each and ranks #6 on the survey of UHPAS (Ultra-High Performance All Season tires. If I was going to replace the OEM tire in the first year on 19"rims, this is what I would choose.

HOWEVER! The Toyos we have are not too bad, at least by OEM standards. They should last at least 18-20k miles. As you've noticed, not too many tire companies are making in our size (yet). If you wait a year you might be able to get the Continental ExtremeContact DWS in a size to fit your stock rims.

ANOTHER REASON TO WAIT is that once you change the rubber, you've forfeited a certain amount of your warranty protection, regarding handling, road noise, etc. If you think these could be issues, keep the OEM rubber and let your dealer deal with it.

And of course, the 3rd reason to wait is to save $800-1200, for the rubber, balancing and mounting.

FIRST POST!!! Picked up a 2014 GT on Tuesday. Traded my 2009 370Z, which will be sorely missed. :(

Welcome jginnane. I hope your are enjoying the CX-5, quite a contrast to the 370Z.

btw - A vast majority of GT owners will find that the Toyo A23 tire lasts far longer than 18-20K. Several posters here have more mileage than that and not one set of 19" tires has been replaced so far.
I have 17.5K on my Toyo tires and they are about 25% worn so far, excellent tires for this kind of vehicle with expected life of 60-65K miles.

Thank you! Yes... there was no pressure anywhere, unless you count the number of times my wife said the word "practical" over a 4-year period. :p

The larger problem was the car was (is) just too good for the roads here in NJ. You couldn't NOT-hoon on the Garden State Parkway. I knew I was going to meet a tall dark man with mirrored glasses sooner or later ... it was amazing I made it 40K miles without points (and only 1 written warning). That Beltronics on the dash paid for itself every 15 days.

Since they changed the Z styling this year slightly (LEDs on the front), it was either get the refresh, or change models. The CX5 was my second choice after a TSX wagon to pair with our 2014 TL (SHAWD+tech+Advance). This CX5 actually has more useful techogadgetry than either Acura. Comparing just to the TSX wagon, their final price was >$7K too high.

I've seen this in the CX5 tire forums, and it's impressive. We're used to replacing crap OEM rubber from numerous car makers, and for where we live, UHPAS-style rubber in the highest-rated (tirerack) is a common occurrence with each new car. On that TL, for example, we demanded to replace the Goodyear RS-As when we went to pick the car up. Wound up with Michelin Pilot Sport Plus, because the dealer had a relationship with his Michelin contact.

Living in coastal NJ, there aren't many snow events each year, but very heavy rainstorms. The sipe pattern we look at is more aggressive than you find on a simple Grand Touring A/S tire. (Living 200 miles north or south, or 70 miles inland near Philadelphia, we'd have different tire picks for the climate differences.)

That's exactly why I mentioned actual wear and performance of 19" Toyo tires, because generalizations about 18-20K life based on other crap OEM tires do not apply. And a lack of aggressive sipe pattern alone is hardly a good reason to rule out this A/S tire.

Hmm... unfortunately, the place where I'd like these tires to perform best is where it's weakest: wet conditions. A bit on the slippery side.

They obviously spec' ed this tire and suspension to get better gas mileage, and that's a trade-off. 35-36# of air is a stiff ride for almost any car, but it helps reduce rolling resistance. Some modern aftermarket tires -- I'm looking at YOU, Bridgestone 960 Pole Position -- are more plastic than rubber.

The Continental ExtremeContact DWS I had on the Z in an inch-wider patch than OEM was a really grippy tire for an all-season. (OEMs were summer treads, naturally). Best tire I ever found. In contrast, the OEM Goodyears on a Honda Element we bought a few years ago were like driving on twin belts of fiberglass. It's a shame to have AWD and then muck it up with $20 tires.

The sipe pattern is important to delay the onset of hydroplaning in heavy rain conditions. But it might not come into play as much on the CX5 because of the relative lightness of the "SkyActive" frame, stiffness of the suspension, and other factors. Still under 1K on my odometer but the car feels acceptably stable at 70-80mph except in modest crosswinds. I've noticed that you have to drive a little hard to get it to track properly; at average highway speeds that car wants to wander a little (that is probably reduced camber). If I had someone who wanted to buy my OEMs I'd happily trade, though (as in the earlier comment) the best replacement I can find today would be the Pirellis.

Yes, agreed any tire that gets this kind of long wear and high MPG will not be the ultimate rain tire (given 60K tire life and best in class MPG). Fortunately hydroplaning is not a issue at safe/legal speeds in the rain with this tire, the tire includes other design elements beyond extra siping to delay onset of hydroplaning in heavy rain.

I noticed the crosswind sensitivity too.
 
Just a note about the word "sipe" or "siping" because it looks like the meaning of the word is being misused.

Tread blocks and rain channels/grooves are molded into the tread pattern during tire manufacture to evacuate water, slush, etc. Sipes are slits cut into the tread and have no width and are not responsible for water evacuation. What sipes do is create more biting edges (especially helpful on snow) but they can also increase traction on wet and dry pavement.

To reduce hydroplaning, choose tires that have a high void/rubber ratio and that are on the narrow side. It also helps if the deeper tread grooves are connected to lateral tread grooves that can channel water outward. Wide tires greatly increase hydroplaning. The lighter the vehicle, all other factors equal, the more prone it is to hydroplaning. Siping a tire will not decrease hydroplaning a significant amount because the sipes cannot channel water away from the contact patch to any significant degree.
