CT5-V Rear tire size

[Smuuth]

I would like to hear comments from anyone who has put 325/30ZR19 tires on the stock rear CT5V Blackwing wheels. Any clearance issues?

My guess would be that they would be too wide for stock rims. Even if they would fit, the contact patch would effectively be about the same as 315's on the same rim. Another thing to consider (if it is true), I've always been told that to maintain handling characteristics, when uprising the rears, you should upside the fronts by the same amount. As an example, 305 to 315 on the rear, then 275 to 285 on the front and maintain the original factory aspect ratio's.

I appreciate your input but I’m looking for comments from someone who has actually done this.

Just trying to pass on good advice given to me by someone that knows a lot more about cars than I do.

Yes, I just did it. I used Toyo R888R 325/30/19. They are amazing and fit, I do have 6mm spacers that I had on previously and I left them in place. Very happy with the outcome. Very good traction with my current mods. Hope this helps

Did you use the spacers to clear the strut or just because you liked the look of the extra poke?

 

[Hurley24BW]

I had them on prior to putting the new tires on and just left them in place. I don't think they are necessary but, they do make it look better in my opinion. For the $40 they cost, not a bad thing to have on hand if you are doing the tires.

Source for the spacers?

Thinking about doing this bc needing to replace the OEM tires but with Michelin Pilot Sport A/S.

I haven't installed 325s, but I theorize they'll fit just fine (and some people such as Hurley have done it) so long as you're at 0 camber.
The 305s have to accommodate track camber which will bring the tires in closer.

Do you need longer studs with 6mm spacers? I know it's not much difference but...

 

[sonny200]

The OEM studs seemed to have enough meat on them for my setup so no need for longer stuffs. YMMV.

This link takes me to a listing for 12mm spacers... Is this actually what you bought or has the listing changed?

Looks like the listing changed as when I took into my Purchase History, it also lists the 12mm spacers. I got the 6mm spacers.

Amazon.com looks like the new link from the same brand for 6mm. Thanks!

Don't we have a 67.1mm bore? How the heck did you get spacers with a 78mm bore to work?

I'd look at ones that are advertised to fit the CT5, if I was buying...

In picture #1 of your post, it looks like you have quite the gap between the spacer and the hub lip. That is NOT safe.

 

[5VBW Nick]

He just used a non-hubcentric spacer. Not my recommendation for sure.

 

[sonny200]

The photo is misleading bc there is no gap. The hub part of the spacer is beveled so it gives the appearance of not hugging the hub lip but it does.
