as the title states, can I reuse my stock 205/45/17 tires on new 17X7.5 rims if I were to buy a new set. specifically 17X7.5 rota boost
I have looked thru a dozen pages on the wheel/tire forum and could find this specific question.
thx

 

Yes, but why would you want to? The stock run-flats are terrible at everything.

 

they're good at getting me from point A to point B and back in one piece, which is all I need right now.
I forgot to ask if there will be any substantial stretching of the tire, will the rim stick out farther than the tire or will it be too close to tell?

 

Nothing you'll really notice. 7.5 is not excessive for a 205

 

I'm sorry, I don't get it. You've lowered your car, done other mods, but want to cheap out on the tires, which are arguably the most significant mod you can do to any vehicle? The cheapest way from A to B doesn't involve a Mini, so you've already blown your argument. Step up and get some nice rubber to really make your car sing!

 

You'll probably have trouble finding a place that can dismount and remount a set of runflats (unless all the hubbub i've heard is wrong).

 

The likelihood of tearing a runflat during dismount is about 1 in 8. Most charge a premium for mount/dismount because of this problem - it allows them to buy you a new tire should they accidentally tear one.

 

i mounted my BBS CVs on my stock runflats. people may disagree with me but i like having peace of mind when my tire blows out. last time i checked i don't have a spare. i have 18s but they were harsher than runflats. so tell me whats more important? but the answer to the original question-- yes they work. there is a small overhang but the bead seals good with no problems.

 

No problem. How many miles on those used runflats? Rough life is about 14,000 to 22,000 miles even with rotation.

Stock sized 205/45-17 tires will fit rims 6.5 to 7.5" wide.

Yes, runflats are difficult to remove and mount so check with the shop.
Will you need TPMS for your new Rotas? Be careful with installation of TPMS, they can be damaged.

Sometimes budget restrictions require using used tires for the time being.

While runflats may not be the most perfect tire for performance driving they suit their designed purpose and a measure of safety in case of a flat.

 

only 7k miles on the runflats which is why I wanted to re-use them, I paid the price when I bought the car to have the 17" upgrade, might as well get the most from the tires at least.
Yes my car does require me to reinstall the tpms on the new wheels which I guess would bring up a new problem of me having to at least partially dismount the rft in order to reuse the sensors anyways. unless of course I wanted to pay 300+ for a new set of sensors

 

after I thought about how much extra trouble it would be for me just to save a couple hundred dollars by stretching an extra 10k miles out of my runflats only to replace them later on anyways, I am just gunna buy a new set of wheels+tires+TPMS and sell my existing wheels without breaking them down to recover the existing tpms.
Now if I could only decide on which tires I should get ... lol
Thanks for the input from everyone, it is what makes the NAM community so great

 

Might I recommend the BF-Goodrich G-force Sport? Fantastic 3-season tires and fairly priced. I've had them on 2 cars now and love em. 215/45-17 *thumbsup*

 

I know I came on a little strong, but I'm glad you did your own calculus and came up with a great solution! My first set of wheels and non-runflats were bought while at Webb Motorsport--I sold my S-lites and runflats to a guy that same hour and drove home happy and hassle free.
Your solution is the best one IMHO. You'll have nice rims, great tires and nothing hanging around in your garage.
Are you looking for a multi-season tire? What about UHP summer tires? I'm recently a big fan of the Yoko Parada Spec-2...

 

Yes they fit, I'd just wait and run stock tires on stock rims until they wear out and you save for decent tires for your rotas. Then switch, and save stock rims for winter use. Switching tires will cost around $80-125 (price of 1 tire) at a shop, why do it twice.

EDIT: Noticed your in California, you don't need winter wheel set. Just buy good summer tires, and save stocker set for long road trips, or maybe for the 1 month of January that it rains a little.

 

yeah I definitely want a ultra high performance summer tire since I really dont do much driving in cold weather in Southern California.
Those BFG G-force sport look pretty good, thanks

 

Really, check out the Parada Spec-2s. You wont find too many harder core UHP tires.
Of course they wont last long, and maybe that's too much of a cost for you?

I like to think about it this way: I take my family to dinner on Saturday and then the movies. It costs me $200. That's one tire... I do that 4x a month... That's a set of tires. I work my **** off...

 

Parada Spec-2s are definitely nice. I find the BF-G a good all around tire including good treadwear without much compromise in terms of wet/dry grip. For the level of driving I do they are excellent... I haven't even been able to find their limit in the dry. Anything beyond that is insanity for public streets.

 

I totally agree...but who drives on public roads? Every road I drive on is mine...except for all those other *******.

Oh, did I say that? Oops-my bad. I guess I view roads as quasi-public goods subject to congestion. Rival but non-excludable.
If you want an "all round" tire then go for it, but if you want a no excuses tire then who cares about tread wear?
It's clearly time for me to go to bed...
sorry.

 

Gandi, are you running 225? or 215?

FOr the price of either parada spec-2 or G force sport, why not upgrade the performance even more with some Falken Azenis or Hankook RS2 tires? Only ten dollars more per tire (on avg.) and awesome tires for the dry climate of socal.

 

WHOAAA Those tires look aggressive! The falken Azenis RT 615 anyways, look like race tires and you're right, only 17 dollars more (http://www.1010tires.com/tire.asp?ti...&pc=28-352-748). The hankook look good also, but a they seem to be out of my price range.
How say you about the Falken 615s?

 

RT-615s are a fantastic tire but they aren't going to last. I know of 2 street-driven sets (roommates' cars) that got 8000 miles before being too bald to drive on... and one set that made it 4000 miles including auto-x. Also, the sidewalls are a bit on the stiff side. But the grip and transient response is fantastic. Definitely a no-compromise tire.

One last thing worth noting - apparently they get soft and greasy pretty quickly when you push them - hence why all the autocrossers spend quite a bit of effort cooling them after each run.

 

Forget 1010 tires, go with edgeracing

Soo much better prices

 

I have RT-615s on my 17" wheels -- second set. Great tire, very grippy, but yes the sidewall is a little stiff and they ride harsh on roads. They do heat up pretty quickly on the track and are dodgy after 15 minutes. But they are very predictable and are superior on the road compared to my Parada Spec-2s. Of course, the Paradas are 215/35/18s so they were not bought for the track...
Oh and Edge Racing is the place. Forget the others.

 

If you are looking into the RT-615s, the you should definitely take a look at the new Dunlop Direzza Star Specs. I used to run RT-615s but once I tried out these new Dunlops, I was sold. They take heat far better, wear longer, don't ride as harsh and have better lateral grip. The new compound for these are a step above the older RT-615s. I bought mine from Tire Rack, along with my new wheels and they were extremely helpful and fast in shipping. I received my wheels and tires mounted in 6 days, shipped to Canada.
