I apologize if this topic has been addressed here in the past, but I could not find enough info to help me make a good decision.

I have have a 2008 Journey Coupe with the 19" TPMS wheels. I have the stock 225/45R/19 on the front and 245/40R/19 on the rear.

I have a couple of questions:

1) Can I run a 245/40R/19 in the front AND rear? Any issues with the larger tire on the front? Any issues with rubbing, traction control, or computer if both tires are the same size?

2) If I can run the 245/40R/19 in the front, do I need a larger tire in the rear to compensate?

I'm a big fan of Discount Tire and looking on their website, there's many more choices in the 245/40R/19 size than the 225/40R/19... I kinda like having all of the options.

Sorry if these are stupid questions, but with so many tire choices out there, I'd like to get as much info as possible.

My driving style is pretty conservative, 80% of my driving is a 80 mile round trip commute on the interstate at 70 mph, the rest is just tooling around town. I will not be doing any track or aggressive driving. Also, I'm in central Texas, so winter issues are not big for me.

Thanks -

I want to know the same thing.

 

Just curious, why are you looking for more options? For what you do, it sounds like you can get some Hankook Ventus or Bridgestone Potenza RE760s and be set at the current tire size.

 

I know you can go as big as 275/30 for the rear tires with 15mm spacers for the g37 vert...

 

^^^^^^ Wrong... it's 275/35x19 for the rear,same as stock dia. Use 245/40 for the fronts. This set up gives you more side wall and overall width... less strech for a more comfort ride,but won't handle quite as well, that's the trade off...been lots of threads on this,use the search bro...

 

Why wont it handle well, if you have a wider tire in the front and wider tire in the back?

 

Good question. The reason that I'm looking for options is that I would like to find tires that are going to give me the highest miles. The Bridgestones that are on the car now are almost bald at 22k miles.

Since I'm not an agressive driver, will not be going to the track or anything like that, I'm willing to have tires with a harder rubber compound, if I can squeeze more miles out of them.

I'm a very conservative driver, with 90% of my driving being an 80 mile round trip daily commute to work, pretty much with the cruise set to 70.

What I'm finding, and maybe I'm not looking in the right places, is that it's difficult to find a tire for the front that offers high miles. So, I was exploring the potential of running a 245/45-19 also on the front so I could buy some higher mileage tires..

So, that's the point of my question...

(Oh, and I have been searching so as not to re-hash old subjects, sorry if I did not find what I was looking for)

Thanks!

You just contradicted yourself.
Same diameter=Same side wall
