If you are replacing all, go for a 245/35F and 285/30R set up this most closely matches factory tire diameters. 275/35 is too tall in the rear. It will look funny and throw of the speedo, slow acceleration.

 

225 Front tired size in my opinion is way under tired for our cars I would go either 245F or 255F. I wouldn't mount two different types of tires so many different variables from compounds to tread designs to the technology used in the tires depending on the age difference between the front and rear. I would hold off mounting any tires until I had completely matched set of tires. Regarding comfort I spoke to 3 different techs from Tirerack that test drove GMax RS that comfort was on par with Indy 500. Nosie, I'm FBO RRR Tune and Tuned intake tires noise is no longer concern cant hear my tires anymore LOL.

 

I'd go with 245/275 or 255/285 if I had the wider 2012+ wheels.
As for the mismatched tires, it would only be for a couple of months. But I'll wait for your report on the Generals.

 

Agreed!!^^^^^225's are waaay too small for the front end of the ISF sitting on it IMO and others as well seem to agree, jump up to 245 or 255 at the minimum and you'll be happy with the decrease in understeer.

 

I recently went 245/35 and 275/30 on stock wheels

 

Current setup with old 255/35F 275/35R

I know longer run 30 size profile tires on my F due getting bubbles on sidewalls of 2 sets of PSS and 1 set of PS2 on bad roads commuting into NYC. Ive been using 255/35/19F 275/35/19R set for while now. 1st for bit larger side walls no longer getting bubbles and slightly better ride quality. Understeer No longer issue, also for me by going with this setup it puts me close to square setup but still staggered I get benefits of both worlds current front tire 10.04 wide, rear tire 10.83 wide.

 

I agree that 225 is too narrow, but I don't track the car, so it's not a big concern for me. Plus, I don't like using tire sizes above the optimal wheel width. If I had the 2012+ wheels, then I'd consider the wider tires.

 

Have you used road force balancing for your tires? I want to know if that's worth it.

 

I have used road force balancing and to me it is worth extra cost. Whenever mounting new tires for the first time I like to use Road Force balancing then use my lifetime wheel alignment with Firestone to ensure everything stays within spec I can take it to get an alignment as many times as I want normally around 5 to 6 times yrs. if i hit bad pot hole and if if feels a hair off I make an appointment and bring it right back to check the wheel alignment.

 

Do you buy your tires from tirerack and use one of their recommended tire installers that has a road force balancer? I've never used their installers before.
Also, when you go in for your lifetime alignment, does Firestone recommend repairs that you don't need? I've read reviews of customers being conned into paying for stuff they didn't really need.

 

For those of you looking for the factory sized front tires, i have 2 bridgestone re760 (i think) that i would sell you for $150. They are at least 85% tread and evenly worn. They're taking up room in my garage so would love to get rid of them. We can figure out a way to ship them economically as well. Located near Sacramento CA. Came off my 2012 ISF when i went wider with ps4s.

Pm me if interested.

 

Yes i always buy tires from tirerack can I sometimes get my tires cheaper from other places like Discount Tires not usually by much and other Distributors yes but I love the customer service of tirerack, free next day shippelng, for certain tires they offer free road hazard insurance for 2 years how they stand by their products. That's why I'm replacing 2 of my current tires they were damaged hitting a pothole when I went to Firestone all I had to do was have them verify the damage via phone call since I had already opened up an incident claim Firestone confirmed the damage and that's pretty much was it. I'll be refunded the price are the two tires. So in essence I'm only paying for two tires. As far as using one of their recommended vendors I've haven't done that I have a shop that I've been using for years that I like and they know me. Now regarding the lifetime warranty and the old up sell trick that's basically a shop by shop bases I have not had tbat experience at Firestone that I go to but then again they know I'm extremely knowledgeable when it comes to cars so they know they're not going to get over on me that may be part of it. My suggestion to you it's go to two or three local firestone's and test them if you know your car needs or doesn't need service in particular area have them inspected and see what they tell you.

Thanks!
I just wish the Firestone shops had a road force balancer.

 

Here are pics with General GMax RS tires mounted. Just like Lou pointed out Y rated to 186mph vs W 168mph they have twice traction rating at AA vs A and 75k mile warranty. I like the way they look, first observation comfort is solid 9+ I'm on RRR LCA and Superpro urethane bushing all the way around upper ctr arms, lower ctr arms, trailing arms front and back and WOW have they improved road quality I can only imagine on car with stock suspension system.

Water same 9+, on par with the more expensive counterparts. In first three days I've already driven in two torrential downpours. These tire were extremely stable felt like I was driving on dry roads. When hitting puddles of water in left lane not hint of hydroplaning. My Cousin was driving F first time we hit bad weather and was amazed these were General tires. He was GM for Goodyear.

Will report back on Dry traction after few hundred miles have been logged. So far so good thou.

 

Thank you very much for the pics and preliminary review.
1. How would you compare the comfort to the other tires you've had in the past (ranking)?
2. What about the noise level?
