Hey guys. Well I don't have much experience when it comes to tyres. All mine have been cheapish until I could afford something decent so I chose to go with the Federal SS595's all round. Before I say anything about the fitment, the SS595's grip really well and I am really satisfied with them.

My rims are 17x8 on the front and 17x9 on the rear.

I used to run a 215/45R17 on the fronts, but after bolting on 25mm spacers I wanted to gain a bit of stretch in the tyre to reduce scrubbing on the guard.

I stayed the same on the rear, running 225/45's, and I am happy with the way they turned out with the Federals.

I had a friend (with experience) suggest me go a profile lower to the 215/40 on the front, so I did.

These are the results. The tyre does not look good at all and you can't even compare the look to the rear.

Does anybody know why this is? And can anybody suggest a solution (perhaps a better fitting tyre size) to go on the 17x8?

If anybody has a decent solution I'm willing to go back to the place and possibly ask to swap the tyres (even if I have to pay a bit more). I have probably only done about 20km max on them so far.

fronts look bulged out, are you sure theyre 215/40?

stick with 215/45/17

dont go to 40 profile, makes it look too skinny.

get rid of the 25mm spacer, its too big, downgrade to 15mm and stick with 215/45.

what offset are your rims? (before the 25mm spacer)

maybe its the way federal designed their tyres thats why it doesn't look at stretched as other tyre makes.

Well I was originally going to go the lower size (205) instead of profile, but I had someone say to me that it's the profile that will increase/decrease stretch etc.

+37 is the offset of the rims.

I think I read somewhere that these particular tyres have a fair amount of lip clearance or whatever, but oh well. Might suss out going the 45 then. More money to spend that I don't have.

Do you think I should risk asking for the 205/45 or just stay safe and go the 215/45 which I used to have.

Ok well as I said I'll see what I can do tomorrow, but most likely I won't be able to exchange it so I'll just have to live with what I got. I will get used to it. Thanks for your input.

Went back today. Basically the guy told me that Federal are very generous on giving the extra lip protection and blah blah, he knew I didn't like it because of the cosmetic purposes but yeah oh well. He says it's a good thing. I'm sure it is, I'll just have to get over it lol.

I had a friend (with experience) suggest me go a profile lower to the 215/40 on the front, so I did.
Information I have suggests that reducing the profile of the front tyres will tend to increase the tendency for understeer.

And why would you skimp on the tyre width by deliberately holding back on fitting the widest possible tyre on the available rim? Looks? The tyres are all that connect you to the road. Not much of a look after the skinny ones let go ...

They aren't ridiculously skinny, and it wasn't entirely for looks, it was so it wouldn't scrub the guard.

I'm convinced it doesn't look as bad as i thought now :verymad:

Yeah nah, reducing width will increase stretch, not profile. Whoever told you that doesn't know what they are talking about.

Agreed with others though, go for a 215/45 next time around. Or if you want a bit more stretch, 205/50.

Stretched tyres are more inclined to understeer though. The sidewall needs to be able to flex to some extent to allow the tyre to maintain grip.

Ideally I'd say next time around go back to 215/45 and run 15mm spacers instead of 25mm.

Front. 17x8 +37, effectively +12 with the 25mm spacer. 215/40R17 Federal SS595 tyre.

Rear. 17x9 +37, no spacer but plans to go 10-15mm. 225/45R17 Federal SS595 tyre.

Got pics? Also are they Federals? As I stated before, Federal seem to be very generous in their rim protectors versus other brands. Also your tyre being the 235 might compensate for being the lower profile.

    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way.

    • Ok, disregard my “rate them” comment, sorry for my unrealistic input
    • OK, now we are ready to get started. You need to remove the air boxes on each side for clearance. The cover is straightforward, undo the clips on the top and lift the front cover out of the rest of the housing. If it is tight you can remove the air filters first. The rear section of the airbox is trickier. On each side you need to remove the Air flow meter wiring which is held to the airbox with a clip; you need to get behind the clip on 2 sides if you want to remove it without breaking it - unclip the harder side and pull on the clip with medium force, then unclip the easier side and it should pop out The airbox is held onto the intake hose with a spring clamp; you need to get a flat bladed screwdriver behind the spring on both sides and pop them outwards. When you have got them in the right unclipped place they will stay there and the airbox slips out pretty freely. Put a rag in the intake to prevent anything getting dropped in there, and also to prevent you seeing that the turbo seal is leaking oil (as they do). Then. The top of the radiator is held by a steel plate, it is secured by 2x10mm and 2x12mm headed bolts . Remove them and remove the plate Also grab the bushings that hold the radiator to the plate on each side so they are not lost!
    • Next, remove the upper and lower radiator hoses, both are held with a spring clamp. While you are under there, tackle the Auto Trans cooler lines.  Again both are held on with spring clamps, and as mentioned above you should cap them on the radiator side with an 8mm cap, and on the car side loop them with a length of 8mm pipe - this will stop you losing a dangerous amount of AT fluid during the rest of the job If you've been meaning to add a sender for AT trans temp, this is a great time to do it; put a sender fitting into the passenger side line as that is the inlet to the cooler/radiator.
    • Next you need to remove the intake duct (as with pretty much every job on these cars), it is a series of clips you gently remove with a flat bladed screwdriver. They do get brittle with time and can break, and I have not found a decent quality aftermarket one that fits (they are all too soft or flimsy and don't last either) but the nissan ones are a couple of bucks each (ouch).  Once the clips are off (either 8 or 10, I didn't check) you lift the intake duct out and will see the reservoirs Undo the line into the radiator side cap (some bent needle nosed piers are awesome for spring clamps) and then remove the 4x 10m nuts that hold both in place.  I didn't get these pics, but remove the line under the radiator reservoir (spring clamp again) then remove that reservoir. Then you can get at the intake reservoir, same thing, spring clamp underneath then remove it. BTW This is a great time to put in a larger (+70%) combined reservoir that AMS makes..... https://www.amsperformance.com/product/q50-q60-red-alpha-coolant-expansion-tank/ They also make an Infiniti branded and part# version if that is your thing
