Default Quick tire size question

I have 6 & 7- 16" Fuchs rims and need new tires now. Standard size for the rims are 205/55-fronts 225/50-rears. Can I put 215/55 or 50 on the fronts and 235/50 or 45 on the rears with the rims I have? I want to put on the widest tires I can. I did a search but could not find the answer. Any input is appreciated.

Here a list of recommended rim widths for Avon tires

http://www.tirerack.com/tires/Spec.j...odel=Tech+M500

a 215 hould be ok on a 6-7.5" wheel
a 245 should be on a 7.5 to 8.5" wheel

Me - the wider the better and less "balloon" I have a 225 on 8" and 245 on 9" -

Jeremy, I just spoke to TireShack.com and they tell me that 205/55 in front is max and that 245/45 is the only option in the rear but with the 245's the car will not feel as nimble as with the 225/50's. 245 sounds wide for a 7"rim no? They have no option fro 215/50-45/16 on fronts or 235/45-50 on rears. I know I've seen them and they even show them on the link you sent me so why don't they reccomend them? They sound like a happy medium. I will keep digging. Looks over handling...hmmmm!

Thanks for the advice Jeremy

I just spoke to a friend with 35 years experience about tire sizes last night and he said that the normal sizes should be 205/55/16 and 245/50/16 for the best handling on fuchs. Certain tire sizes lose too much ground contact. Go for best contact over looks. My opinion...

The rule of thumb I've alwasy gone by:

225 - 6 or 6.5" wheel
235 - 7 or 7.5" wheel
245 - 8" wheel
(now) 255 - 9" wheel

I just put 245/40-17's on my 9's, and the sidewall tucks back in toward the tread. A 255 would have been a much better choice for that wheel.

I've run 245/45-17 on 8" wheels, but I know people who have run them as narrow as 7" (looked horrible, didn't handle any better than a 225 honestly).

I'm told the PO had 245's on the 8" rear C2 wheels I have, FWIW. The 205/55-16's on the front 6" wheels bulges out noticeably, where the 225/50-16's have a straight up sidewall on my 8's. Every tire's different though, so look at the manufacturer's recommendations closely.

245 is too wide for a 7 " wheel

If I was putting tires on 16" wheels - 6 and 7's - I would go Front 16" 205/55-16 - Rear Optional 16" 225/50-16 Kuhmo Ecsta MX. I know a few folks that run these tires and have excellent luck with them

Gost,

Remember that wider rubber is only better if supported by the appropriate rim size. A tire that is too wide for a given rim, while it may fit, will not have adequately supported sidewalls which will lead to more sidewall flex, negating some of the "advantage" of the wider tire. Furthermore, said tire will have a bowed tread area which not only will wear the middle of the tread more quickly than the outer, but also puts less contact patch onto the road since it is bowed instead of straight, again negating that "advantage" of wider rubber. If what you want is more traction, you get it from better (more costly and quicker wearing) tires of the appropriate size, not by cramming more rubber under the wheelwells. And for 6"/7" rims, 205 and 225 are not just the "standard" sizes, they are the optimum sizes. Hope this helps.

Edward

Differences in opinion are a-plenty with tire sizing. I'm thinking if I want wider rubber and better traction that the way to go would be to move the 7's up front with 225/50's and get 8's for the rear and put 245/45's on them. It would mean a hefty outlay of cash though which is scarce these day's. Perhaps the best option is to stick to the 205/55's and 225/50's and as Edward and Jeremy state, put good rubber on them. Perhaps PS2's or Yoko's AVS Sports or S02's or Kuhmo Ecsta MX. I've also heard really good things about the Avon Tech M500. Anyone hear or have experience with the Avons? Great pricing and excellent performance as well.
Thanks so much guy's...again.

Guys on the SHO Forum are playing with the M500's and love them so far. I just bought the MXs for my 84, had a couple of days street & a little track time yesterday. For a street tire, pretty grippy, fairly quiet but gave a little bit of feedback just before the breakaway point.

I think the tire game has evened out a little. I'm not sure you can go wrong with either the Avons (which I know a few guys that run them, just don;t have a ton of miles on them) the Kuhmos MX, probably next step up on the money ladder would be the Yoko AVS sports and then the S02's - But the money goes up from there too. I run the yokohamas AVS sports. They are excellent rain tire (we get a little rain in Florida) They complain a little before they let go (good for driving on the track) and they have lasted relatively well.

I think it's down to the Mx's or the Avons. I know it's vain but the tread pattern is blah on the Avon's. The yoko's look awesome and the MX's are cool as well. Perhaps I just answered my own question.

Ciao fellas

So I ended up getting the Yokohama AVS ES100 205/55/16 up front and 225/50/16 in the rear. I know it's a level down from the PS2 and AVS Sport and even the MX but I'm not running the car on track or very hard so the ES100"s look great and perform admirably for the price. By the way I got them at Pep Boys who price match and beat by 5% any price out there even on the web, just print out the price sheet and bring it into them. You also get free mounting and hi speed balance with the purchase of 4 tires which I did. And if that was not enough of a bargain I also got a $50 gift card for free with this coupon I've been holding which was out of one of their promo calenders which cost a buck.
Total cost installed for the Yoko's was $ 321 plus the $50 gift card so really it was $ 271......is that remarkable or what?
So all of you can give them a try as well. Just print out Tire Racks quotes and run like the wind to Pep Boy's or I'm sure others will do it as well ie: AutoZone etc.

That is an INCREDIBLE price, and you'll be happy with ES100's I think.
