Hi Guys,

I need some good, good ugly comments. on fitting 245 tyres on a 9.5" rim (TE37 17"/9.5").

I know its a bit of a stretch altho there the tyres I want... Falken RS-V04 racing semi-slick.

Is this a good idea. I did have Dunlop D01J 265/40/17 on there previous but there all chewed up. I've been recommended these Falkens and thats the biggest size they make in 17.

It might interfer with quater mile runs. as there won't be much flex?

but good for track days..they are for a gtr.

input? am i crazy? pay the extra and get the D01's? any one ever used the RS-V04s?

thanks in advance.

shouldn't make too much difference. Best fit for 245 is 8.5ins. RS-V04 is designed for track....sidewalls should be much too stiff for drag. The bit of extra stretch should make them even stiffer. General opinion seems to be ...Falkens are good value for money but a couple of secconds a lap slower than the D01's

I've heard good things about the R1R's, says they wear well, warm up very quickly so are good for low lap events like sprint days where you usually do about 5 laps max. I believe they grip better than the Falkens too

fitted ok guys..rims do stick a bit out over the tyre..should be fun..side ways are nice and tight. would be good if my car was for doorift.

anyway..hopefully they dont give me too much slip off the line.

And it would be a 255/40R17 that you should recommend, not a 45 in that case.

I run a 255/40/17 on a 9.5" rim, Federal advises the tyre is for 8-9", there is no stretch on the 9.5" or difficulty getting them on, they just fit :D

      RS Four doesn’t mean it has Hicas, by old RS 4 didn’t have it. It was an optional extra.  just stick your head underneath and look

      Hi everyone, I own a 2001 Nissan stagea nm35 with the VQ25DET, and I'm just trying to figure out if it's the 250T RS FOUR V (hicas) or the 250T RX FOUR (IRS Type) I have no owners manual and the vehicle is de-badged, does anyone know how to identify the difference, I briefly looked it up and I seen no difference.

      Question about BoV on RB25DET NEO

      By Kapr · Posted

      Yeah the hybrid you mean one of these? https://youtu.be/kL518ThmzSw?t=118 Yes that one that only vents is that i post above( GReddy FV2) right? That FV2 has some type of screw/valve where you can control how "hard" the spring would...but i think even on the hardest it would not be "good"...i would need to restrict this "more"...i consider this 🙂  And car should be ok(or rather same) with this like with no BoV?
