Growing more unsatisfied with current run flat tires, anyone have recommendations for 205x40x18 replacements ( non-run flats)
Thanks

 

 

As long as you don't have a lead foot, the Pirelli Cinturato's were decent tires, but low tread life. I've got Bridgestone A/S RFT right now with 450 tread life and they're doing a great job. I commute on the highway and can 100% say that the Bridgestone's grip the road far better in rain than the Pirelli's did. I have not driven the Michelin's yet, but if you're looking for great all around performance, IMO it was not there with a sport tire.

 

These are what I am looking at but in a 215x40x18

 

 

I replaced the summer runflats with Michelin A/3+ 205/40-18 tires. After 5000 miles, the tires still look new. The ride and handling are outstanding. You don't have a lot of alternatives in that tire size. I considered going with 215s, but the larger size in the AS/3 actually has a lower load rating. Maybe that's why the ride seems soft on the 215 s. Also, the 205 Michelins are noticeably wider than the Dunlops that I replaced. Tire preference seems to be very individual. I put a lot of miles on my car(daily driver) and have found ownership of Michelins ( all-season ) to be fairly economical when you add in how long they last. ( also, I rotate my tires every 5000 miles).

 

Recently when I was looking for a used Mini cooper I came across "run flat tires". Never heard of them before So my mini doesn't come with spare tire and the car has Hankook tires, but I haven't checked the model # or if they are run flat. So how different is the ride quality of RFT tire and a standard one?

 

Run flats (RFT) are most always going to be a stiffer ride than a 'normal' all-season type tire, since the sidewalls have to support the vehicle's weight without any air pressure. They may not be any stiffer than an 'extreme summer' type of tire, which will have a very stiff sidewall to give it better cornering capability at the sacrifice of straight line comfort. All RFT tires should have a symbol on the sidewall to designate their run flat capability. If your Hankook tires are not RFT and you are w/o a spare, hope you have AAA or something equivalent, as you won't have any options with a flat tire out on the road.

Here is a good source for the RFT symbol from Tire Rack's site: https://tires.tirerack.com/tires/Run%20Flat%20Symbol

 

I would have to take a picture of the tire and then find out what kind it is, but I do know it is Hankook with size: 205/45/R17 and also believe they are original tires that came with the car

 

My previous MINI was a '15 S with the Hankook 205/45x17 runflats. Hankook has a different designation for their runflats. In my humble opinion, those tires are total CRAP. At the time, I replaced with a Bridgestone runflat and those tires were better in every aspect. On my new MINI JCW I had to replace the runflats with a non-runflat because there weren't any runflats available in a all season version in 205/40x18.

 

I pulled the run flats within a week of buying my R56 and F56. I have roadside assistance through my phone company and insurance company and I carry a "Slime Kit" with compressor in the boot.

 

I agree the Hankook tires that are on my car do not represent a good quality tire, at least not in the ride quality. The car is a bit stiff by itself on top of that these tires don't make the ride quality any better I am driving in the MID mode, to make the suspension a bit softer on the roads that don't have smooth asphalt. So if my car doesn't have a spare tire, than I most likely would need to replace my tires with the same RFT, but a different brand. I won't need to tires at least till the next fall/winter, but I did some searching online and it seems that Bridgestone(as you mentioned), Continental, Pirelli and Michelin would be good replacement.

I was thinking about going with a standard "all season" tires as well, but don't know if it will make the side wall softer which would hinder the cornering ability?

 

All seasons best tire I'd say is the Continental DSW06. Amazing dry grip, amazing wet performance, and amazing snow performance. For summer only I'd go with the Michelin Pilot sport 4S. Amazing dry performance and amazing wet performance. Two different compounds in the tire that let it perform the way it does. Youtube reviews on it.

 

It shifts to 2nd within rolling a foot or 2. I feel it shift.

 

My local shop does have some Continental tires, but I will check what kind. Do you know if this Continental DSW06 tire is RFT or standard?
Never had Michelin on my cars as they were more expensive than others, but if they make all season tire that fits my car, I will take a look

 

I checked tires on my car and they are Hankook Ventus V2 Concept 2 205/45/R17 and I can't really see if they are RFT or standard and there is no info online about them being run-flat. The issue is that I don't have a spare tire and I thought the tires on my car are run-flat. I do have tire repair kit that my car came with. Anyone had these kinds of tires?

 

Check the Hankook website. They have a different designation on their tires for runflats.

 

I bought 18 inch OEM rims to switch to summer non runflat tires. Michelin pilot does not come in a 205/40r18 in a summer tire. Only tires I could find are Bridgestone and Pirelli. Both get terrible reviews for tread wear. Really disappointed in the selection. My intent was to put winter tires on my stock 17’s and summer on my 18’s. Person I was talking to at tire shop said a 225/40r18 would fit. I was concerned about rubbing so ditched that idea. I will be putting on Pirelli P Zero for now. Maybe I will get two summers out of them. I drive a 19 JCW. What do you guys use for summer tires on 18’s?

Rims my hubs got me for my birthday

Nice +1^^

 

 

The Continental extreme in a 215 gets very good reviews on tire rack compared to Pirelli. Was not sure a 215 would work. I usually just buy Continental runflats when I had to replace a tire. Moving to summer tires is adventurous for me :-)

 

 

I switched my order to 215's Continental. Guy at discount tire said they should work fine. I get high anxiety when I need to make a decision on something I am not sure about. Thanks for the feedback. Appreciate it.

 

I run the Conti ExtremeContact Sport and they have been fantastic.

 

There is pretty much minimal difference running 205/45/17 and 215/45/17 as far as I understand. I wanted to go 215 size, but using the tool that calculates any changes in odometer reading, it reported small amount of inaccuracy. I believe I would stick with original 205 when time comes
