Tyre width choices please help!!
Hi there I have a set of 7.5 inch wide revolution s they 205 40 17s but they look to thin for my liking my options are 215 40 s ,235 40 s or 225 45 s.
Any body run any of these sizes on 7.5 inch rims ?? Or have any pics so I can have an idea of what theyou look and feel like ?? Cheers Car is a v3 type r |
No 205/45/17 would probably be the right size but its a horrid size to get hold of so most people go for 215/40/17 as they are much easier to obtain.
On a classic I would not go any wider than 215 or you may have issues with rubbing. |
As above 215/40/17, I run Vred ultrac sessantas in this size on my classic with 17x7.5j wheels.

215/45 x 17

Mine are 215/40/17, I've got a spare ST2 and tyre in the garage if you want to try it to see how it looks.

The US got 205/55 x16
So, what about a set of Michelin Pilot Sport 4 in 215/45 x17 Your speedo would read exact though. |
To put some numbers to it:
OEM 205/50 R16 = 1921mm rolling circumference. For a '+1' 17" upgrade: 205/40 R17 = 1872mm r.c. (2.5% difference) 215/40 R17 = 1897mm r.c. (1.2% diff.) best overall choice 205/45 R17 = 1937mm r.c. (0.83% diff) closest to OEM 215/45 R17 = 1965mm r.c. (2.3% diff.) |

They also got 2.5 engines and different ratio gear boxes, but don't let that stand in the way of justifying incorrectly sized tyres ;) A percentage difference of 2.1% is not recommended. Recommending a 45 profile on a 215 is just plain wrong stating the speedo would remain unchanged. :nono:
You've got 25ish gear sets to go through now, to check none of them were used in the US and Australia, as well as JDM. I wrote that the speedo would read 'exact', which it does. As opposed to reading 'over' which is the case on a 205/50 x16. On uneven roads, like here, there's a performance advantage in a more compliant tyre, hence my suggested increase in aspect ratio. |
:wonder:
That the classic and newage speedo read over? or That a more compliant tyre is beneficial on an uneven road surface? or Both |
What are the biggest size rims 17 and 18 to fit the standaard type-r.

Examples: As requested by the OP - these are 215/45 on a 7 x17 - Eibach P11L springs |

215/45x17 @bonesetter - don't know if he still uses this size? |
Is that a REEEALLY badly oxidized red car...Or a really dodgy flat matt red vinyl wrap?! :eek: |
