I frequently see claims of the Falken FK452 being a wonderful tyre, only for someone to come along and rubbish that. Because of the big split in opinion, it was extremely difficult to come to an informed decision without actually driving a car with them on. One conclusion I came to was that they weren't absolutely terrible and they were at least worth the money.

I've been looking to get rid of the runflat tyres on my car for some time now due to the crashy ride and the snappy breakaway. So, having been made an offer I couldn't refuse, 4 brand new FK452's for £360 fitted and balanced, I had them put on. Since I've had a change of circumstances and am constantly broke nowadays, having a full set of tyres for less than half the price of the Bridgestone Potenza runflats was very welcome.

The first observation made within 3 seconds of moving after having them fitted was that the ride is like night and day. Small bumps in the road are soaked up rather than amplified up your spine. You could decribe the ride comfort as "bareable" now :D

I'll not comment on the grip for the first couple of hundred miles until the tyres were gripping properly. The steering feel however was noticeably different. I've heard people harp on and moan about how the electric power steering in the Z4 was absolutely terrible and shocking and how it ruined the car. They were over exaggerating. It was nowhere near as bad as they were making it out to be. Most of them were regurgitating crap they'd read on a forum.
Maybe not though. Maybe they drove a Z4 with FK452s fitted. The steering has become noticebly more vague and sloppy. There is less feedback and there appears to be a delay in turning in while the tyre flexes. It's almost like driving on tyres made of chewing gum.

It's not THAT bad but it's definitely a major downfall. Maybe it's the same with all non-runflat tyres.

After a couple of hundred miles I think I can begin to appraise the grip. I'm waiting for it to rain so my opinion on wet grip will have to wait.
Dry grip is good. In fact, it's pretty good. It's not great. It's certainly more than acceptable when I'm pushing on. On the Z4 I'd imagine the Falkens are at the higher end of their performance requirement and taking this into consideration they perform very well. When taking roundabouts hard, the DSC light blinks a bit more often. The front end seems to break away a bit sooner before the rear gives up. The big difference between these and the runflats is the progressiveness of the loss of grip. With the runflats, you'd go from 100% grip to about 2% in the space of a millisecond. With the Falkens, it's much more progressive and predicatable, making the driving more enjoyable in my opinion.

When I have the traction control turned off but leave the DSC on, the car is significantly better and more fun to drive. You can feel it being right on theedge and maybe even kick out the back end and get a bit of a slide going in a very controllable manner. I've been enjoying a bit of roundabout surfing much more than I used to!

Whilst the bottom line is that they grip less in the dry, they provide a better platform for all out driving. In an emergency situation though, I dunno.


So, to summarise:

- They aren't as amazing as a lot of people make them out to be.
- The do not grip as well as higher end tyres.
- The sidewalls feel like they flex a lot and can make the steering feel vague.
- Your e-penis is docked 3 inches.

+ They aren't as crap as some people make them out to be.
+ Cheap.
+ Massive increase in ride quality compared to runflat tyres.
+ They can make the handling more predictable and dare I say it, more fun.
+ Cheap.


If you can justify the extra £££ on higher quality tyres then go for those. They will grip better. They will probably handle a bit better and they will probably feel better.
If you can't justify the £££, the FK452 isn't a bad shout.
 
A bit less of an appraisal than I've given them since day-1. I found them to be superb on my Leon Cupra R, and wouldn't hesitate to put them on the 330d when it comes round to needing tyres.

They have IMO an almost identical feel to Eagle F1 GSD3's, that being a touch soft on the sidewall, but great grip in the dry, far better than adequate in the wet.
 
Yeah I agree with that, I had a set on the Evo once and yes they were a very good tyre for the money but I went back to Toyo Proxies T1-R's which cost a bit more but once scrubbed in are a better gripping tyre and the wet grip is very impressive.

Certainly cant go wrong with the 452's though for the money! :)

Oh while were talking tyres I would stay away from Yokohama Parada Spec II's though, I tried these out as well and were shocking, understeeeeeeeeeeeer lol

Now, for the 330d, T1-R's were actually cheaper, and garbage.

I've also had both T1-R's and FK452's on the LCR, and the 452 was a better tyre all round.

Hmmm its quite funny how different people rate tyres differently, I found the Toyo's to be much better on the track (maybe because they are running hotter?) but we are comparing them on totally different cars and most prob a different driving style, plus I run some neg camber on the front for improved turn in.

Same issue as the Yoko Parada's though - I was recommended to try them by a mate who runs them on his Fiesta ST and I was impressed but they failed badly on the Evo, just seemed to invoke more understeer and wet grip was laughable, talk about going sideways lol

Just thought actually my mate who I work with has used various Dunlops and Bridgestones on his E46 325 and asked me about tyres and I said try the T1-Rs and he loves them, says they are the best hes had! Again funny how people rate tyres differently!

One last quick thing I will say though is the Toyos DO need a fair bit of scrubbing in before you get the best out of them :)
 
I haven't personally tried the FK452, but I had 451s on the scooby and they seemed a pretty good tyre for the price, wet weather grip could have been better though.

As for the Toyo T1r, it's a great tyre, I had a set on the RX7 and my Golf came shod with a set. Predicably however, I'm going to pimp the Kumho KU31, they are the best tyre I've tried in this price range. I fitted a set to my Golf to replace the Toyos and they are noticeably better, especially in the wet.

/stuck record :o :D

A note with the general steering feel but especially turn in, I have to run about 2-3 PSI more with the 452s. This improved things a great deal.

I think they are fantastic value, and not really a bad tyre at all - grip is decent, although I've not had a chance to really test them in the wet yet.

That said, I probably wouldn't buy them for the ST again, purely because, the ST being a mostly weekend car these days, I want something that 'feels' a bit sharper and more exciting - I think I'd find this in something like Ultrac Sessantas. That said, I wouldn't hesitate to put them on say the Mondeo for example.

I have found them to be excellent in the dry and pap in the damp!



My Toyo T1-R just fell apart on track but were quite good on the road.
 
i had toyo for a short time on the front of my primera GT and they seemed okay.

drexel what size khumos do you use?

camskil has a 11% off the 205/16 Toyo T1s so they are only about a tenner more than the Khumo...which to eat...?
 
I got a few q's. What is your "what if I have a flat" strategy now, what with changing from runflats? Have you gone the mobility kit route, i.e. tyre weld and a compressor? Will you be relying on breakdown cover to get you home if the tyre weld doesn't work, if so is this BMW breakdown cover as per the warranty?

Have you told your insuruers? If so did they kick up any fuss about it, demanding letters from BMW to state it does not alter performance or handling etc?

Is it possible to fit a space saver spare wheel in a Z4?

When I made a similar move in my Z4 I had a can of tyre weld, an RAC membership and if I was going for a longer drive I could just chuck a spare wheel in the back (a full sized 18 inch wheel fits in the boot). Luckily I didn't need to use any of the three before selling the car a few months ago.

195/50/15 on the Golf. As I said, in my experience the Kumhos perform better all round than the Toyos, so my choice would be the Kumhos.
 
I rated these on the 350z, cheap, fun, predictable and lasted forever.

Got new Conti PS2's fitted on the Z4M as of last week and they are fantastic, despite the rather eye watering price.
 
Ride comfort versus turn in response.

You can't have both I'm afraid. Toyo T1Rs ruined the steering and handling on my S2000. Bridgestone RE050A made it so much better.

The Z4 s35i I drove had 30 profile RE050A RFT tyres on. The slightly bump under power would upset the thing, so I can see how non RFTs are going to be better on your Z4M
 
On the 200sx I found they offered similar performance to the Eagle F1. My first set were quite a bit cheaper but the difference isn't as much now so for the last set I went back to F1's
