Default 18" on all four corners?

Is anyone running the same wheels/tires on front and rear? Will need new tires and possibly wheels for my xf roadster. I was thinking 235/40ZR18 on 18 x 8 wheels. Tire life will be better as four wheel rotations are possible. Also does not sacrifice much width in rear. Thoughts anyone?

I was thinking about different options too. Has anyone tried running 275/40R19? I think having a bit more rubber would look good.

I am new to these cars but you could possibly run those in the back but definitely not up front. I am looking for something the same on all four corners.

If this forum has been in place for 13 years and there are already many topics, any chance new folk have joined in the 13 years and they may have new or different experiences. I always find it interesting when us new folk come along we are told to "Search". Yes, that is a good thought and many of us have used the Search function to find the topic ended years ago. Sometimes new ideas come to light when a topic is brought back up. Just Curious?

Thanks for the slap down DENNIS. Please, can I have another!

It seems to me when someone gets a new car or project, they want to talk about it. I thought that's what forums are for. My post was asking for opinions not for tutorials.

Natemo, do the search and post to it, it will bring it back to the form. It has tutorials and discussions. That is what a form is.

My searches lead me to believe that 19" wheel/tire on the front will most likely encounter rubbing on a bolt in the wheel well during aggressive turning/cornering. I've seen several posts of I believe 19" tires shredded.

Personally, I'd stick with stock sizes and not risk the headache or waste of money and ultimately going back to 18" on front.

Sorry for the confusion, I was talking about just the rear tires and going +2 to 275. I know it will affect the speedometer but not greatly. I too considered 18" all around but decided to stay original in rim size.

the 275/35 is only
Diameter difference:
0.55" (2.07%)
over the stock 255/35
so you are correct. You can live with a 2% difference.

At 70 indicated you'll be doing 71.4 - no problemo.

With proper rim offset, I believe you could even go 245/40/18, as long as you don't lower it, or autoX, or track it.

There are several reasons to do a search but the one you're overlooking is that the search will bring up existing threads about your subject that contain the information you seek. After reading the existing thread(s), if necessary, you can then add a post to an existing thread rather than starting a new thread. Doing it that way will help reduce "clutter" on the forum and ultimately will help all forum users to search for and more easily find the information they need.

Good point Red Dog!

I just had 275/40R19 tires put on my original rear rims. It's a very tight fit and I wouldn't recommend it. I'll go back to the factory size next time.

The "40" profile tire is too high. Size 275/35R/19 would work fine . . .

These are 285/35/19 on the rear and they fit just fine with a little more width and height
Protects the rim from curbrash and provides a bit more rubber on the road for traction

That's what I'm running on the rear as well. IMHO it fills the wheel well much better.

VALK, those look good. How close are the tires on the front lower panel? I can't tell from that angle.

Stock size tires on the front
285/35/19 tires on the rear
No mods to the suspension at all

Here are some side views and a rear shot
