The texture limit appears to be already smashed. I can load MIPs (~122 MB) with a vertical resolution of ~16384, by replicating the texture vertically. The horizontal resolution has limits,
Rendition hardware supported horizonal resolutions of around 2048 in Windows (RRedline), but the limit may be lower in DOS. I'll dig up a list of valid horizontal resolutions. The vertical resolution can't be scaled higher than 16384 because modern OpenGL hardware doesn't support textures bigger than 16384x16384, the wrapper wouldn't be able to handle it. Original Rendition hardware doesn't have vertical limits, other than memory.

Using this build of Dosbox-Rendition which supports 1.5 GB of RAM:
MD5: 0f9542b3008fb4fcd009c9527381f718
and these patched version of ICR2 (1200 MB) texture buffer:
MD5: 37b018cb355a3e9800716cec17f86319
For good measure this version of Denver with 16384 textures (43MB) can be loaded along with the carset. Performance is horrible, but it loads:
MD5: b80e6f54b7a1df30f6df1f4a11cbf663
So tracks with higher resolution textures should be possible, but there's a limit to how many total MIP map levels can be loaded. That looks to be my next task.

This track wouldn't reduce with
tredit <path to unpack dat dat> -reduce -convert <output folder>
It needed this version of TREdit:
MD5: bb57f14e880ffe665168b9b5106f88c6
used with the command line:
TREdit.exe <path to unpacked dat> -reduce -maxmips <maximum number of mipmaps per texture> -convert <output path>
e.g.
TREdit.exe c:\temp\mexicodat -reduce -maxmips 5 -convert c:\temp\mexicoreduce
(Apologies to Vogon tincup, I should have figure this out sooner)
Mexico City (Max 5 mip maps per texture) Now Rendition Ready:

Two different versions of the Belle Isle tracks in Rendition Ready format:
Belle Isle '95:
belle Isle '98:
Rendition Ready versions of these two tracks:
MD5: 2940c0211d8d2cb57a4439d4b61e06f8
MD5: 6fd2dfc2c11a3d407fb43607baff29bb

*************************************************
RReady Alpha 19, May 2025 (1.0.42, fully tested alpha release)
*************************************************
MD5: 51d669ac897fb52a01d001b9f711eab1
- Fixes Windows 7 crash bug introduced in March.
- Improves Formula 1 performance and allows for anti-aliasing to be disabled for this game.
- Games which use paletted textures (16 colour) should see slight speed improvement. There may be a slight improvment in ICR2 with the stock tracks, but these tracks always ran well.
- Team Apache: - Adds a workaround for nvidia drivers (after Win11 24H2 and the equivalent for Windows 10) which causes the game to freeze at the end of the first intro video. (Thread de-prioritization from real time)
-Team Apache: Campaign mode text rendering should be correct
- Team Apache: Loading progress bars for instant action missions should always load.
- Interstate '76 and Niitro have a new pre-configured DxWnd build for High an Regular DPI displays. Please see help file for details.
