Interesting info. I have a set arriving today and the shipping weight for a pair of 255s is 48 lbs, while 285s come in at 56.10 lbs.

 

275/35/19 is not the correct size for the rear of the ISF. 275/30/19 is.

I think I'm getting ready to pick up a set of the PS4S very soon so I want to confirm the correct size that I want. I have stock 08' wheels and want a slightly wider tire, but I absolutely dont want a "bulged" look. Will the PS4S work in the 245/35/19 front, and 275/30/19 rear with no buldge? I know the PS2's fit, but wasn't sure about the PS4S.

thanks!

 

If we agree that 255/35/19 is the correct size then it is debatable whether 275/30/19 is more correct than 275/35/19. One size causes approx. 2% positive error while the other approx. 2% negative error. Ride height changes 1/4in either higher or lower for the chosen tire.

The 30 series tires:
give very slightly quicker acceleration.
have a bit harsher ride
speedometer will read faster than you are going
slightly better handling

The 35 series tire:
give you very slightly better gas mileage
have a bit softer ride
speedometer will read slower than your actual speed.
will fill the wheel well a bit better.

I have never tried either size but based on the above characteristics I am leaning toward the 275/35/19 tire when I get new ones.

 

^^^^Your characteristics for the 35 series tire are wrong on points 1 and 4. How will it improve gas mileage? Because it's taller and heavier, the gas mileage should be a wee bit worse. 275/30/19 fit a 9" wheel just fine.

But your in Canada after all and your free to do as you wish.

Absolutely for me when paired with PSS's!

 

dont do it--it will look too tall. I've seen the 245/275 combo in person and it looks quite good.

 

I just got my car back from the dealership yesterday evening. I had some warranty work done and brand new set of tires installed. I went with MPSS 245/35/19 & 275/30/19 on stock 2011 wheels. What a difference! coming from stock sized Toyo Proxes 4 plus. I still want to get more seat time with these set of tires. So far they feel really good.

 

I've had pretty good performance with 255/35/19 up front and 275/30/19 in the rear.

 

I went 275/35/19 rear and 245/35/19 front. I'm quite happy with the results. Fills out the wheel wells very nicely, although now I wish there was a little less gap up front. In the end it is a very minimal difference as newgsman said it's only 2% but i'd rather have a little more sidewall personally.

 

I was think of going with 245/40/19 for the front. That would be closer to 275/35/19 in terms of diameter. The front gap would also be a bit less than 245/35/19.

 

I was thinking the same thing, but I wasn't sure if going with a taller tire up front would cause rubbing issues. Wish I would have given it a shot now as the rear is absolutely perfect with zero gap although I am going to need to roll my fenders, has me wanting to lower the front a bit to compensate but it doesn't look bad at all.

 

245/40 will look ridiculous. I went with a 235/40 against the advice of the forum members and they were right...it looked too tall and I ended up selling them and going back to stock size in front, even though I took a hit financially. I could literally feel the front of the car higher off the ground when driving. A 245/40 would be even worse.

 

If you went with 235/40/19 with 275/30/19 then for sure the fronts will look very tall because they will be almost half inch taller. You are right a 245/40/19 front will definitely look ridiculous with a 275/30/19 rear.

A 245/40/19 front tire however should not look so bad with a 275/35/19 rear given that they are both virtually the same diameter.

 

A 275/35 will only make the whole set up look even more ridiculous. The 235/40 looked bad INDEPENDNET of what the rear looked like. Now, having a 245/40 series in front and a 275/35 series rear will be a decision that you regret...it'll look like an SUV.

For the record, my rear is a 265/35 Porsche OEM tire with the same tread width as a 275 and this looks fine. But, having seen the 245/35 and 275/30 in person on 08-11 rims, this will be my next set up.

I know you may think that the small increase in tire diameter won't appear significant to the eye, but it will. And you can truly notice the difference in nod height even with the 235/40!
